Abstract

A power switch includes an OC detection circuit, a UV detection circuit, and an OC indication circuit. The OC detection circuit detects an over-current in the power switch, provides an OC flag in a first state when no over-current is detected, and provides the OC flag in a second state when the over-current is detected. The UV detection circuit detects an under-voltage in the power switch, and provides a UV fault indication in a third state when the under-voltage is not detected, and provide the UV fault indication in a fourth state when the under-voltage is detected. The OC indication circuit provides an OC fault indication in the third state when the over-current flag is in the first state, and provides the OC fault indication in a fifth state when the over-current flag is in the second state. The UV fault indication and the OC fault indication are configured in a wired-or to provide a common fault indication.
