Abstract
A switched power rail monitor compares voltages provided by a switched power rail and a power source to detect a predetermined differential indicative of a fault at the switched power rail. A switched power rail fault is communicated to a power manager to take corrective action, such as cutting off power to information handling system components. In one embodiment, a pair of bipolar junction transistors monitor the voltage differential to send an enable signal if the differential is within limits and a disable signal if the differential exceeds limits.
