Description

The TPS2383B is a power sourcing equipment power manager (PSEPM) that are compliant to the power-over-ethernet (PoE) IEEE 802.3af Standard. A PSEPM port can discover, classify and deliver power to a powered device (PD) capable of accepting PoE twisted pair cable. The TPS2383B is fully programmable by the user. This allows for the detection and powering of both fully compliant 802.3 devices as well as custom detection of legacy devices.
