Pin Description
Pin NO. NAME I/O
Description
Negative power supply for this IC. Also acts as detection pin for the battery
1
GND Input
connected between VIN-GND.
Nch-FET gate connection pin for discharge control. Switches gate OFF when
2
GD Output excess discharge is detected, and for current protection. Switches gate ON when
excess discharge is detected in normal state.
Detection pin for voltage between CS-GND. Detects excess discharge using Nch-
3
CS Input
FET (discharge control) ON resistor and discharge current.
Control pin for Nch-FET for charge control. Switches FET off by activating an
4
OC Output
external transistor when excess charging is detected.
5
N.C
This pin sets non-induction time for overcharge detection. It charges the capacitor
6
TD Input
connected between TD-GND with a fixed current during overcharging.
7
VCC Input Positive power supply pin for the IC.
8
VIN Input Detection pin for the battery connected between VIN-GND.
