Function
Power Good output: Open drain output which indicate that output voltage has reached
90% of input voltage
Supply Input: Input to the power switch and the supply voltage For the IC
Switch Output: Output of the power switch
Fault Output: Active LO, open drain output which indicates an over current supply under
voltage or over temperature state.
