TPS23752PWPR TI PoE PD Controller | 20-HTSSOP | 802.3af/at, 2-Event Classification

Product Overview

The TPS23752PWPR is a highly integrated Power over Ethernet (PoE) Powered Device (PD) controller from Texas Instruments. It complies with IEEE 802.3af/at standards and supports 2-event classification for high-power applications. Housed in a compact 20-HTSSOP package, it provides a complete interface for PDs requiring up to 25.5 W of power. The device integrates a hot-swap MOSFET, current sense, and a PWM controller for isolated DC-DC converters, simplifying design and reducing BOM cost.
