Overcharge detection output pin

4

OC

On overcharge, an external transistor is driven to turn off the charge-control FET (N-ch)

5

N.C

6

TD

Overcharge detection dead time setting pin

7

VCC

Positive power supply voltage pin

8

VIN

Voltage detection pin for battery connected between VIN and GND

Notes : Overcharge mode : Battery voltage > overcharge detection voltage

Normal mode : Overdischarge detection voltage < battery voltage < overcharge detection voltage,

discharge current < overcurrent detection level

Overdischarge mode : Overdischarge detection voltage > battery voltage

Overcurrent mode : Discharge current > overdischarge detection level=CS-GND voltage > discharge

current turn-on resistance (discharge-control FET)
