Electrical Specifications
Pin Descriptions
VIN (Pin1, 2)
The input power source. The VIN can withstand 30V input.
GND (Pin 3)
System ground reference.
WRN (Pin 4)
WRN is an open-drain logic output that turns LOW when any
protection event occurs.
NC (Pin 5, 6, 12)
No connection and must be left floating.
EN (Pin 7)
Enable input. Pull this pin to low or leave it floating to enable
the IC and force it to high, which will disable the IC.

TEST CONDITIONS
VB (Pin 8)
Battery voltage monitoring input. This pin is connected to the
battery pack positive terminal via an isolation resistor.
ILIM (Pin 9)
Overcurrent protection threshold setting pin. Connect a
resistor between this pin and GND to set the OCP threshold.
OUT (Pin 10, 11)
Output pin.
EPAD
The exposed pad at the bottom of the TDFN package for
enhancing thermal performance. Must be electrically
connected to the GND pin.
