PIN FUNCTIONS
10-pin
QFN
Name Description
1 VIN Input Power Source. VIN can withstand 30V input.
2
GND,
Exposed Pad
System Ground. Exposed pad and GND pin must be connected to the same ground
plane.
3
FLT
Open-Drain Logic Output. This pin turns LOW when any protection event occurs.
4 NC No Connect. Keep it floating.
5 NC No Connect. Keep it floating.
6
EN
Enable. Leave this pin floating or pull it below 0.4V to enable the IC. Drive this pin
higher than 1.5V to disable the IC.
7 VB
Battery Voltage Monitoring Input. Connect this pin to the battery pack positive
terminal via an isolation resistor.
8 ILIM
Over-current Protection Threshold Setting. Connect a resistor between this pin and
GND to set the OCP threshold.
