Abstract
A power supply over-voltage protection (OVP) system includes a transistor having a source terminal configured to connect to a power supply output terminal of a power supply. The transistor has a drain terminal configured to connect to a system load, and a body diode forward voltage drop. The power supply OVP system further includes a low voltage monitor circuit connected between the source terminal and a gate terminal of the transistor, and a high voltage monitor circuit connected to the source terminal and configured to be connected to a control circuit within the power supply. The low voltage monitor circuit is configured to monitor a source voltage at the source terminal and provide a gate control signal to the gate terminal. The high voltage monitor circuit is configured to monitor the source voltage at the source terminal and provide a power supply control signal to the power supply.
