Fully charged   batteries are detected when the battery voltage peaks. In   fact, a voltage drop of 0.25% with respect to the top value   is detected. Fast charging is initiated at ‘power on’ or at   ‘replaced batteries’. The switch is continuously on,   providing that all protection levels are met. At battery full   detection, the charge current is duty cycled to reduce the   average charge current to a lower level, keeping the   batteries fully charged but at he same time assuring long   battery life. In Fig.3 the battery voltage during fast charge   is plotted.   Supply block   For correct start-up, the IC supply current is limited to   35 µA (typ.) until the start-up voltage of 6.4 V is reached   (standby mode). Thereafter, the operating supply voltage   VP has to be within the window of 5.45 to 11.5 V, meaning   that there is no need for an external voltage regulator to   supply the IC.   The supply block delivers the following outputs:   • With the help of an external resistor (pin Rref), a   reference current is obtained which defines the   accuracy of all IC timing characteristics   • Externally available 4.25 V stabilized voltage source   (Vsource). This source is used internally to supply a large   part of the circuit and can be used to set the NTC biasing   and to supply other external circuitry with a maximum   current of 1 mA. Protection information is provided via   VS, to design a dual LED indicator   FUNCTIONAL DESCRIPTION   A block diagram of the TEA1104; TEA1104T is illustrated   in Fig.1   Mode latch   • Power-on reset pulse resets all digital circuitry after a   start or restart, due to an interrupted VS.   The Mode latch determines if the system is in the fast or in   the slow charge mode.   • Fast charge is active at:   – power switch-on and battery connected   – temperature between minimum and maximum value   – battery insert   1996 Feb 26   4 Philips Semiconductors   Objective specification   Cost effective battery monitor and fast   charge IC for NiCd and NiMH chargers   TEA1104; TEA1104T   • The battery voltage is sensed each ‘cycle time’. The   cycle time is defined as:   Open battery protection   When the rechargeable battery is removed, the output   voltage Vbat will rise to a high level. The ‘open battery   protection’ block will detect this voltage and the charge   current will be switched off. A digital filter prevents false   open battery protection. The open battery signal   (Vbat > 3.6 V) must be present for a duration of at least   4 clock pulses.   – Tcycle = 2 exp16 × tosc   • The ‘inhibit time’ is the time that the charger current is   disabled, after which the battery voltage is sensed in a   currentless way.   – tinhibit = 10 ×tosc   Battery sampling takes one oscillator period for each   cycle interval.   Battery monitor   – tsample = tosc   One or two cell packs can be connected directly to Vbat   (battery connection) without an external resistor divider. At   larger cell packs the battery voltage must be scaled down   to a voltage range of 0.81 to 3.6 V. It is also possible to   take a tap on the chain of batteries. Battery full is   recognized by voltage peak detection (Vpeak), meaning a   decrease of 0.25% (typ.) with respect to the top value.   Keeping in mind a battery voltage range of 0.81 to 3.6 V   and an accuracy of 10% at Vbat = 2.4 V for battery full   detection, means that the internal ADC has to be 13 bits.   Several filters are included to prevent false full detection.   The series resistance of the battery and battery connection   can cause battery voltage fluctuations and therefore it is   necessary to stop the charging before sensing; this is   called the ‘inhibit time’. This will be performed   • The ‘disable time’ is present to correct start-up with flat   or polarized batteries. During the disable time, the   battery full detection is not active.   – tdisable = 2 exp −5 × time-out   The timer is reset by battery full detection, but is on hold   during the temperature and battery-low protection modes.   Temperature protection block   Temperature sensing is achieved by using a cheap   thermistor. Two temperature windows are built in:   • If the temperature at power-on reset is above the   maximum temperature protection level, the trickle   charge current is active. The same applies for   temperatures below the minimum temperature. Fast   charging starts when the temperature is in between the   minimum and the maximum temperature levels.   automatically via the regulation output pin LED. The   charging is stopped for ten oscillator periods at the end of   which sampling is performed. The battery voltage will now   be sensed in a currentless way.   • If the temperature is between the maximum and   minimum temperature at power-on reset, the fast charge   current level is active. If the temperature sinks below the   minimum temperature level, again the trickle charge   level is active. At rising temperature, the fast charge   current is latched off at the ‘cut off’ temperature level.   Timer/oscillator   The oscillator has a sawtooth shape.   The period time is defined by: tosc = K ×Rref × Cosc   The oscillator frequency is used in the timer block. In this   block several important signals are created.   To avoid switching on and off with temperature, a   hysteresis is built in for low temperature level. If the   temperature protection is not necessary, pin ‘Negative   Temperature Coefficient resistor’ (NTC) must be   connected to pin Rref.   • Time-out for protecting the fast charge process in time.   Time-out is normally chosen to be 25% longer than the   associated fast charge time. So for a one hour charge   time, time-out = 1.25 hours. The relationship with the   oscillator period time is:   Battery low protections   – Time-out = 2 exp28 × tosc   When the battery voltage is less than 0.81 V, the circuit   assumes that there are short circuited batteries and the   charge current is reduced to the trickle charge level. If the   batteries are flat, the trickle charge current is able to raise   the battery voltage within an acceptable period of time,   after which fast charging starts.   • The duty factor in the trickle charge mode: The duty   factor is fixed to 1⁄40, meaning that the average:   – Itrickle = 1⁄40 × Ifast   – ton = 3⁄4 × 2 exp9 × tosc   – toff = 2 exp14 × tosc   . 1996 Feb 26   5 Philips Semiconductors   Objective specification   Cost effective battery monitor and fast   charge IC for NiCd and NiMH chargers   TEA1104; TEA1104T   In non mains isolated systems, the current source can be   switched via the auxiliary winding (see Fig.6) using the   TEA140X power plugs.   Output drivers   Several output drive possibilities are supported by the   TEA1104, to limit the fast charge current and to indicate   the mode that the charge is in.   In the application section, an example is shown driving two   LEDs that are indicating fast charging, protection during   fast charging, full status and removed batteries. It is also   possible to output the same information via one LED only.   In mains isolated systems, output drive current is available   for a bipolar or MOS switching device. Moreover, current   regulators can be driven (see Fig.4).   MGE355   V bat   full   detection   t I charge   fast charge (I   ) trickle charge (I   /40)   fast   fast   Fig.3 NiCd battery characteristics during a 1.25C charge cycle.   output   output   output   LM317   LED   LED   LED   TEA1104   TEA1104   TEA1104   MGE356   Fig.4 Output drivers.   1996 Feb 26   6 Philips Semiconductors   Objective specification   Cost effective battery monitor and fast   charge IC for NiCd and NiMH chargers   TEA1104; TEA1104T   START   no   no   V > 11.5 V   6.2 V < V < 11.5 V   V s < 5.25 V   s s yes   yes   yes   total reset logic   clamp at 11.5 V   circuit non-active   ≤ 45 µA   set TIME OUT (e.g. 111 min)   I = 25 mA   DDmax   I o DD   set T   T (e.g. 48 C)   o max   circuit active   (e.g. 20 C)   min   circuit active   V < 0.81 V   bat   or T   no   < T   bat   bat   min   or T   > T   max   (note 1)   yes   trickle charge   I / 40   fast   yes   FAST   dual LED   indication   (note 2)   no   blinks   yes   FULL   OFF   FAST   blinks   0.81 V < V   < 3.6 V   no   bat   (note 3)   and   < T   T < T   max   min   bat   (note 5)   yes   FAST charge   stop charge   total reset   open battery   o set T   (e.g. 55 C)   cut-off   yes   FAST   ON   FAST   no   no   dual LED   indication   dual LED   indication   OFF   yes   yes   FULL   FAST   FULL   OFF   FAST   ON   OFF   OFF   -∆V   ≥ 0.25%   and   > 3% TO   o C bat   no   no   no   T ≥ 55   TIME OUT > 111 min   bat   (TCO)   (TO)   t dis   MGE359   battery is FULL   trickle charge   I / 40   fast   (note 4)   (1) Vbat < 0.81 V due to empty or flat battery.   yes   (2) For single LED application see Fig.7, for dual LED   application see Fig.6.   FAST   no   dual LED   indication   (3) Vbat > 3.6 V due to system occurrence or an external   blinks   inhibit via pin Vbat   . yes   (4) Release via reset.   FULL   ON   FAST   (5) Tmin = VNTC ≥ 2 V; Tmax = VNTC ≤ 1 V;   OFF   Tcut-off = VNTC ≤ 0.81 V.   Fig.5 Flow chart of the TEA1104.   7 1996 Feb 26   Philips Semiconductors   Objective specification   Cost effective battery monitor and fast   charge IC for NiCd and NiMH chargers   TEA1104; TEA1104T   LIMITING VALUES   In accordance with the Absolute Maximum Rating System (IEC 134); note 1.   SYMBOL   VP   PARAMETER   supply voltage   CONDITIONS   MIN.   −0.5   −0.5   MAX.   +13.2   UNIT   V V V VoLED   ViNTC   LED output voltage (pin 8)   VP   +5   negative temperature coefficient resistor   input voltage (pin 2)   −0.5   Vi(OSC)   Vi(bat)   VRref   Isource   IoLED   IRref   oscillator input voltage (pin 7)   battery input voltage (pin 4)   reference resistor voltage (pin 5)   output source current   LED output current   −0.5   −0.5   −0.5   −3   − −1   +5   V +5   V +5   V +0.01   25   mA   mA   mA   mA   mA   reference resistor current   battery current   +0.01   +1   Ibat   −1   − VP   supply current   25   Ptot   total power dissipation   Tamb = 70 °C   TEA1104   − 0.5   W TEA1104T   − −20   − 0.35   +70   W Tamb   Tj(max)   Tstg   operating ambient temperature   maximum operating junction temperature   storage temperature   °C   °C   °C   +150   +150   −55   Note   1.

The   basic application diagram as illustrated in Fig.6 which is   based on the application diagram illustrated in Fig.7 with   some additional components; a 2 LED charge status   indication has been provided.   The duty factor of the pulse is 2.5% of ttrickle. This duty   factor also applies to the charge current as the charge   current switch is driven by the LED output. Therefore, the   average trickle charge current is Ifast /40. The Vbat input   can be adapted to the battery voltage via the resistor   dividers R1 and R2. When an NTC thermistor has been   incorporated into the battery, the minimum, maximum and   cut-off temperature levels can be set with the resistors R3   and R4. For an NTC with a common sensitivity of 3965   and adjustment resistor values R3 = 13 kΩ, R4 = 20 kΩ   the minimum, maximum and cut-off temperatures will be 5,   42 and 50 °C respectively.   For charging a battery within one hour the charge current   rating should be as follows:   Required minimum charge current = battery   capacity × 1.2/charge time.   Therefore, for a 1 Ah battery the external charge current   supply has to deliver at least 1.2 A.   The flow chart of the TEA1104; TEA1104A is given in   Fig.5. The load state of the batteries can be displayed by   one or two LEDs. The flow chart is not to be regarded as   sequential. Each mode of operation is a purely separate   continuous process.   TEA1104 settings   The fast charge back-up timer period, time-out, has to be   set in relation to the expected maximum charge time.   Normally, a safety back-up time is chosen approximately   25% longer than the maximum expected fast charge time.   For a one hour charger the time-out period can be set to   1.25 h.   Table 1 Dual LED indication   CHARGER   MODE   VLED   VS   LED 1 LED 2   Time-out relationship with the oscillator repetition time is   as follows;   Fast charging   low   high   high   on   off   off   Fast charging   protection   low/high   on/off   t osc = time-out (h) × 3600/2 exp28   tosc = 17µs for time-out = 1.25 h   Full   low/high   high   low   off   off   on   off   (trickle charging)   tosc is set with the combination of Cosc and Rref;   Battery open   high   where tosc = 0.93 × Rref × Cosc   .

Dwell times vary   between 50 and 300 seconds depending on heating   method. Typical reflow temperatures range from   215 to 250 °C.   SOLDERING   Introduction   There is no soldering method that is ideal for all IC   packages. Wave soldering is often preferred when   through-hole and surface mounted components are mixed   on one printed-circuit board. However, wave soldering is   not always suitable for surface mounted ICs, or for   printed-circuits with high population densities. In these   situations reflow soldering is often used.   Preheating is necessary to dry the paste and evaporate   the binding agent. Preheating duration: 45 minutes at   45 °C.   WAVE SOLDERING   This text gives a very brief insight to a complex technology.   A more in-depth account of soldering ICs can be found in   our “IC Package Databook” (order code 9398 652 90011).   Wave soldering techniques can be used for all SO   packages if the following conditions are observed:   • A double-wave (a turbulent wave with high upward   pressure followed by a smooth laminar wave) soldering   technique should be used.   DIP   SOLDERING BY DIPPING OR BY WAVE   • The longitudinal axis of the package footprint must be   parallel to the solder flow.   The maximum permissible temperature of the solder is   260 °C; solder at this temperature must not be in contact   with the joint for more than 5 seconds. The total contact   time of successive solder waves must not exceed   5 seconds.   • The package footprint must incorporate solder thieves at   the downstream end.   During placement and before soldering, the package must   be fixed with a droplet of adhesive. The adhesive can be   applied by screen printing, pin transfer or syringe   dispensing. The package can be soldered after the   adhesive is cured.   The device may be mounted up to the seating plane, but   the temperature of the plastic body must not exceed the   specified maximum storage temperature (Tstg max). If the   printed-circuit board has been pre-heated, forced cooling   may be necessary immediately after soldering to keep the   temperature within the permissible limit.   Maximum permissible solder temperature is 260 °C, and   maximum duration of package immersion in solder is   10 seconds, if cooled to less than 150 °C within   6 seconds. Typical dwell time is 4 seconds at 250 °C.   REPAIRING SOLDERED JOINTS   A mildly-activated flux will eliminate the need for removal   of corrosive residues in most applications.   Apply a low voltage soldering iron (less than 24 V) to the   lead(s) of the package, below the seating plane or not   more than 2 mm above it. If the temperature of the   soldering iron bit is less than 300 °C it may remain in   contact for up to 10 seconds. If the bit temperature is   between 300 and 400 °C, contact may be up to 5 seconds.   REPAIRING SOLDERED JOINTS   Fix the component by first soldering two diagonally-   opposite end leads. Use only a low voltage soldering iron   (less than 24 V) applied to the flat part of the lead. Contact   time must be limited to 10 seconds at up to 300 °C. When   using a dedicated tool, all other leads can be soldered in   one operation within 2 to 5 seconds between   270 and 320 °C.   SO   REFLOW SOLDERING   Reflow soldering techniques are suitable for all SO   packages.   Reflow soldering requires solder paste (a suspension of   fine solder particles, flux and binding agent) to be applied   to the printed-circuit board by screen printing, stencilling or   pressure-syringe dispensing before package placement.   1996 Feb 26   14   Philips Semiconductors   Objective specification   Cost effective battery monitor and fast   charge IC for NiCd and NiMH chargers   TEA1104; TEA1104T   DEFINITIONS   Data sheet status   Objective specification   Preliminary specification   Product specification   This data sheet contains target or goal specifications for product development.   This data sheet contains preliminary data; supplementary data may be published later.   This data sheet contains final product specifications.   Limiting values   Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134).
