Abstract
An electronic device includes a rectifier bridge that includes an input configured to be coupled to power over Ethernet (PoE) power sourcing equipment (PSE), and an output. A transistor is configured to selectively couple the output with a load. The electronic device includes a maintain power signature (MPS) device, and a control circuit. The control circuit is to maintain the transistor on when a load current is above a threshold, source current from the rectifier bridge to the MPS device when the load current is below the threshold, and switch the transistor to a diode configuration when the load current is below the threshold.
