Description
1
GND
Input
Negative power supply for this IC. Also acts as detection pin for the battery
connected between V
IN
-GND.
2
GD
Output
Nch-FET gate connection pin for discharge control. Switches gate OFF when
excess discharge is detected, and for current protection. Switches gate ON when
excess discharge is detected in normal state.
3
CS
Input
Detection pin for voltage between CS-GND. Detects excess discharge using Nch-
FET (discharge control) ON resistor and discharge current.
4
OC
Output
Control pin for Nch-FET for charge control. Switches FET off by activating an
external transistor when excess charging is detected.
5
N.C
6
TD
Input
This pin sets non-induction time for overcharge detection. It charges the capacitor
connected between TD-GND with a fixed current during overcharging.
7
V
CC
Input
Positive power supply pin for the IC.
8
V
IN
Input
Detection pin for the battery connected between V
