PIN FUNCTION DESCRIPTION
Pin
Symbol
Description
1
Cell Voltage
This input is connected to the positive terminal of the cell for voltage monitoring. Internally, the Cell
Voltage Sample Switch applies this voltage to a resistor divider where it is compared by the Cell Voltage
Detector to an internal reference.
2
Test
This pin is normally not connected and is used in testing the protection IC. An active low at this input
resets the internal logic and turns on both MOSFET switches. Upon release, the logic becomes active and
the cell voltage is sampled within 1.0 ms.
3
Ground
This is the protection IC ground and all voltage ratings are with respect to this pin.
4
Discharge Gate Drive
Output
This output connects to the gate of discharge switch Q2 allowing it to enable or disable battery pack
discharging.
5
Charge Gate Drive
Common/Discharge
Current Limit
This is a multifunction pin that is used to monitor cell discharge current and to provide a gate turn–off
path for charge switch Q1. A discharge current limit fault is set when the battery pack load causes the
combined voltage drop of charge switch Q1 and discharge switch Q2 to exceed the discharge current limit
threshold voltage, Vth(dschg), with respect to Pin 3.
6
Charge Gate Drive
Output
This output connects to the gate of charge switch Q1 allowing it to enable or disable battery pack
charging.
7
VCC
This pin is the positive supply voltage for the protection IC.
8
Charge Pump Output
This is the charge pump output. A reservoir capacitor is connected from this pin to ground.
