Function
Supply Input: Input to the power switch and the supply voltage for the IC
Ground
ON Control Input:
Fault Output (FPF2503-FPF2506): Active LO, open drain output which indicates on over
current supply under voltage or over temperature state.
Adjustable Current Limit Setting Resistor (FPF2500-FPF2502): An external resistor
connected between this pin and ground sets the current limit value.
Switch Output: Output of the power switch
