Pin Descriptions
VIN (Pins 1, 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 (Pins 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 to disable the IC.
