Abstract

This application discloses a powered device (PD) used for power over Ethernet (PoE). The PD includes an Ethernet port and a rectifier circuit. The rectifier circuit includes a first control circuit and a second control circuit, the first control circuit is configured to: control a first MOSFET and a second MOSFET, skip turning on the first MOSFET and the second MOSFET at a PoE detection stage, and turn on at least one of the first MOSFET and the second MOSFET at a PoE power supply stage. The second control circuit is configured to: control a third MOSFET and a fourth MOSFET, turn on at least one of the third MOSFET and the fourth MOSFET at the PoE power supply stage, and skip turning on the third MOSFET and the fourth MOSFET at the PoE detection stage.
