SINGLE CHIP BATTERY CHARGER CONTROL IC FUNCTIONAL DESCRIPTION
1. Adapter Constant Voltage Control VDET pin supplies this block with voltage to control voltages of both adapter and protection during charge.Control reference voltage ,applied by REFOUT pin , is constant. Output voltage is generated from dividing the adapter voltage by external two resistors connected to VDET pin and the modification of the dividing ratio of these resistors by CHG pin changes the voltage of Adapter/Charge. 2. Charge Constant Current Control block IDET pin supplies this block with voltage to control constant current during charge and is controlled directly by the voltage of 0.1 resistance ,connected to low side,for the current detection.Control referential voltage is set by ratio between external two resistors connected to REFOUT pin.Buttery temperature detection control performs switching quick and trickle by selecting ADJ pin as follows:. Quick charge : ADJ1pin Trickle charge : ADJ2pin Adapter constant voltage control ,written in 1 clause, is capable of invalidating this control. 3. Charge constant voltage control block VBIN pin supplies this block with voltage to control constant voltage during charging. Output voltage of VBOUT pin,gained differentially from battery voltage,supplies to VBIN pin. Control referential voltage ,applied from REFOUT pin, is constant. 4. Charge SW driving Circuit control block This block controls SW pin,driving transistor for charging SW. Charge off : SW=OPEN Charge on : SW=L 5. Battery voltage differential gain block Battery voltage input from B+/B- pin directly and outputs to VBOUT pin after differential gained. The gain of Amplifier is 1/3 VBOUT=1/3(VB+ - VB-) Input of OPAmp for differential gain or feedback resistance depends on external circuit element. 6.

7. Detection of battery connection /battery temperature This block detects the battery connection and the battery temperature by the input voltage dividing between thermistor inside battery package and resistances outside REFIN pin. Each referential voltage for detection is set by dividing REFOUT pin voltage by inside resistances. The dividing circuits are grounded to THS pin connected directly to - terminal of battery to prevent input voltage of TH pin from changing by the current of external circuit. <1> Battery connection detection The battery connection is recognized in case the resistance of the thermistor connected to TH pin is less than the following: Thermistor resistance(Rth): less than approximately 100k Detecting timing is as follows: 60msec * 2 times =120msec(Foc=3.41KHz) <2> Battery temperature detection This block controls to switch charging after detecting the battery temperature by the dividing ratio between resistance pulled up and thermistors. Detecting timing is as follows: 60msec * 2 times =120msec(Foc=3.41KHz) For further details,read the 20 clause. 8. Over discharge detection block In case the voltage majored before starting to charge is less than the detection voltage,the over discharge mode is taken over before waiting.It continues to wait until the battery charges from external circuit and the charge mode is taken over after the voltage becomes more than the detection voltage.The differential gain output voltage of the battery is majored at this block. The referential voltage for detecting is set by the dividing ratio between resistors connected to the REFOUT pin. The Over Discharge detection voltage (V Blow) is 4.0V. This detection is disregarded during charging. The detection timing is as follows: 300msec *4 times = 1.2sec. (foc=3.41kHz) 9.Over Voltage detection block NG mode is taken over ,in case the voltage majored before starting to charge is more than the following voltage.The referential voltage for detecting is REFOUT output voltage. The over detection voltage(Vbhigh) is VREFOUT. This detection is disregarded during charging. The detection timing is as follows: 300msec *4 times = 1.2sec. (foc=3.41kHz) 10 The charge completion detection block The charge completion mode is taken over in case the charge current in charge mode is less than the detection current. This detection depends on the gained current output. The referential voltage for detection is set by the dividing ratio between resistors connected to ADJ3 pin.This detection is discharged except during charging. The detection timings is as follows: 600msec *8 times = 4.8sec. (foc=3.41kHz)

11.The Adapter Over Current mode The Unusual mode is taken over in case the current majored in the adapter mode is less than the detection current. The referential voltage for the detection is set by the dividing ratio between the resistors connected to ADJ0 pin. The detection is disregarded except in adapter mode. Detection timing is as follows: 3.0sec *4 times = 12sec. (foc=3.41kHz) 12. LED Driving block This block controls LED driving pin by each mode. Adapter mode : off No Battery Connection mode : off Charge mode : During Display Timer counting ~~~on/off After Display Timer counting ~~~on Over Discharge mode : on/off Temperature Protection mode : on/off Charge Completion mode : off Charge NG mode : off Unusual mode : off *LED on/off timing is 1/1.5Hz(0.9sec. on/0.6sec. off) respectively. 13. The regulated referential power supply block The charge of output REFOUT pin voltage depends on inside bandgap voltage as the reference and the gained voltage of the changeable resistance connected to REFOUT pin. This block uses REFOUT output voltage as reference and controls the charge constant voltage and every reference both inside and outside. REFOUT typical voltage : 1/3 of the battery charge constant voltage 14. Adapter detection block The Adapter connection input switches the mode as follows: OPEN(H) detection : Adapter connection GND(L) detection : No Adapter connection The detection timing is as follows: 12msec. * 2times = 24msec(Foc=3.41KHz) 15. Adapter mode control block The detection of adapter connection changes all modes except unusual mode into adapter mode. The Next mode after adapter mode depends on the previous mode. Previous mode -> Next mode No connection -> No connection Charge -> Charge(after initialization) Over discharge -> Charge(after initialization) Temperature Protection -> Charge(after initialization) Charge Completion -> Charge Completion Charge NG -> Charge NG *The detection of No battery connecting during Adapter mode disregards the previous mode and takes over No battery mode.

16. PC driving block The control to the PC pin,for driving Photo Coupler, depends on each control of Adapter constant voltage,Charge constant current and Charge constant voltage. Vcc side : Photo Coupler off, output voltage rising GND side : Photo Coupler on, output voltage falling 17.PC short control block The Unusual mode is taken over in case the over current is detected during the Adapter mode. This block is capable of fixing PC output into Vcc side and shutting down the primary power supply current. All input and detection are disregarded in the Unusual mode. Only reset is capable of returning from Unusual mode. 18.AC check detection block AC Power off is recognized and Adapter mode is taken over, in case the PC pin voltage continues more than the following voltage in cert ain period: AC check voltage (Vacchk: Vcc-0.8V) The detection timing is as follows: 60 msec. * 16times=960msec.(Foc=3.41KHz) 19. Timer Block (1) Waiting timer after battery connection This block pauses for following period from the battery connection detection to starting charge , so that every input is decided. Waiting time : approximately 3.2 sec(Foc=3.41KHz) (2) Display Timer Counting the following time after starting to charge switches display from on/off to on. Display timer : 30 minutes (Foc=3.41 KHz) In trickle charge mode,this timer pauses to count. This timer resets counting to initialize before charge restarting,in case the charge as counting or pausing stops because of the charge to the adapter mode or the temperature protection mode. Example of Display Timer <1>In case charging starts in quick mode, Counting End Charging Counting End Quick Counting 30min | | on/off on Charge Completion | off

(3) Charge Timer Charge NG mode is taken over after counting the following time after charge starts.
