Pin Functions

PIN I/O DESCRIPTION
NO. NAME
A1 VOUT O Output of the power switch
A2 VIN I Supply. Input to the power switch and the supply voltage for the device
B1 GND – Ground
B2 CL I Current limit selection. CL high is 155-mA current limit, CL low is 70-mA current limit, and CL floating is 30-mA current limit.
C1 OC O Overcurrent output flag. Active-low open-drain output that indicates an overcurrent, supply undervoltage, or overtemperature state.
C2 ON I On/off control input
