Electrical Specifications
Pin Description
VIN (Pin 1)
The input power source. The VIN can withstand 24V input.
GND (Pin 2 )
System ground reference.
NC (Pin 3)
No connection and must be left floating.
FAULT (Pin 4)
FAULT is an open-drain logic output that turns LOW when
any protection event occurs.
EN (Pin 5)
IC enable pin. Pull this pin to LO to enable the device and
pull it to HI to disable.
VB (Pin 6)
Battery voltage monitoring input. This pin is connected to the
battery pack positive terminal via an isolation resistor.
ILIM (Pin 7)
Overcurrent protection threshold setting pin. Connect a
resistor between this pin and GND to set the OCP threshold.
OUT (Pin 8)
Output pin.
EN Input Logic LOW
EN Internal Pull Down Resistor
FAULT Output Logic Low
FAULT Output Logic High Leakage Current
POWER MOSFET
On-Resistance (Note 4)
