TEA1104; TEA1104T
GENERAL DESCRIPTION The TEA1104 is manufactured in a BiCMOS process intended to be used as a battery monitor circuit in charge systems for NiCd and NiMH batteries. It is especially designed for cost effective compact consumer applications. The circuit is able to detect fully charged batteries by currentless battery voltage sensing. Several output drive functions are available to control the (reduced) trickle charge current to keep the batteries full with maximum life expectations. The battery full detection is backed up by two independent mechanisms to make the system fail safe; maximum time and maximum temperature.

INTRODUCTION The operation of the TEA1104; TEA1104T is explained with the aid of the application diagram illustrated in Fig.7. An application note (AN95085) is available describing the versatility of the TEA1104; TEA1104T. An external power current source charges the batteries via an electronic switch which is controlled by the TEA1104. The TEA1104 monitors the battery voltage. 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. FUNCTIONAL DESCRIPTION A block diagram of the TEA1104; TEA1104T is illustrated in Fig.1 Mode latch 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
* Trickle charge is active if: - battery full is detected - maximum time is exceeded - maximum cut-off temperature is exceeded after the initial phase. Supply block For correct start-up, the IC supply current is limited to 35 A (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 * Power-on reset pulse resets all digital circuitry after a start or restart, due to an interrupted VS.

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. Battery monitor 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 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. Timer/oscillator The oscillator has a sawtooth shape. The period time is defined by: tosc = K x Rref x Cosc The oscillator frequency is used in the timer block. In this block several important signals are created. * 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: - Time-out = 2 exp28 x tosc * The duty factor in the trickle charge mode: The duty factor is fixed to 140, meaning that the average: - Itrickle = 140 x Ifast - ton = 34 x 2 exp9 x tosc - toff = 2 exp14 x tosc.
TEA1104; TEA1104T
* The battery voltage is sensed each `cycle time'. The cycle time is defined as: - Tcycle = 2 exp16 x 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 x tosc Battery sampling takes one oscillator period for each cycle interval. - tsample = tosc * 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 x 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. * 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. 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. Battery low protections 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.

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 mains isolated systems, output drive current is available for a bipolar or MOS switching device. Moreover, current regulators can be driven (see Fig.4).
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. 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.

APPLICATION INFORMATION A guideline for the settings of TEA1104 and its external components selection is given based on an example of a 1 hour charger for a 4 cell NiCd or NiMH battery pack. 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. For charging a battery within one hour the charge current rating should be as follows: Required minimum charge current = battery capacity x 1.2/charge time. Therefore, for a 1 Ah battery the external charge current supply has to deliver at least 1.2 A. 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. Time-out relationship with the oscillator repetition time is as follows; tosc = time-out (h) x 3600/2 exp28 tosc = 17s for time-out = 1.25 h tosc is set with the combination of Cosc and Rref; where tosc = 0.93 x Rref x Cosc. Rref can be chosen between 13 and 120 k, but a 27 k resistor is recommended. The oscillator capacitor can be calculated which is 668 pF; the nearest higher practical value is 680 pF.
TEA1104; TEA1104T
In the trickle charge mode the LED output will pulsate with a repetition time; ttrickle = 2 exp14 x tosc = 0.28 s. 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 k, R4 = 20 k the minimum, maximum and cut-off temperatures will be 5, 42 and 50 C respectively. 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. Table 1 Dual LED indication VLED low low/high low/high high VS high high low high LED 1 on on/off off off LED 2 off off on off

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. 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). DIP SOLDERING BY DIPPING OR BY WAVE 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 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. REPAIRING SOLDERED JOINTS 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. 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.
TEA1104; TEA1104T
Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. WAVE SOLDERING 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. * The longitudinal axis of the package footprint must be parallel to the solder flow. * 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. 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. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. REPAIRING SOLDERED JOINTS Fix the component by first soldering two diagonallyopposite 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.
