PIN 7: SEL3- perature protection function. PIN 8: TMR- al resistor PIN 9: MODE- f 1 PIN 10: SEL2 - completion of fast n 10. IN 12: GND- Power ground. PIN 14: LED2- tting of SEL1 and SEL2 PIN 15: ICON- harging current to PIN 16: DSW- in application informations). PIN DESCRIPTIONS Tri-level input, determining the period of peak voltage timer. (See 0∆V cut-off sectio application informations.) Divided battery voltage inp sense the battery voltage. Push-pull output, used to control an external transistor to discharge the battery. DIS is active high when the SS678 mode. The battery cell temperature is represented as a voltage input to the SS6781B at this pin. The acceptable voltage range of VTS pin is 0.29VCC to 0.72VCC. The battery temperature is regarded as too high if the voltage of VTS pin is lower than 0.29VCC, and is otherwise regarded as too low if the voltage of VT higher than 0.72VCC. PIN 5: VCC- Power supply input at 5V±10%. For adjusting the slope of ∆T/∆t. Acceptable voltage range for this pin is approximately 0.28V to 3.8V. If voltage higher than VCC-0.3V, the function Determine the acceptable voltage range of VBT pin and mode of tem Determine the period of safety timer with an extern connected to GND. Determine the mode o operation for the SS678 B. Tri-level inputs, that jointly control the LED display mode and the duty of trickle charge after the charge. PIN 11: SEL1- The same as Pi P PIN 13: LED1 & Open-drained outputs used to indicate the battery charging status. Two modes of display are available, depending on the se pins. Open-drained output, used to control the c the battery. Controlling the function of discharge- before- charge. (See discharge- before- charge subsection |
