TPS2388RTQT TI Power Management IC | 56-QFN (8x8) | 4-Channel PoE PSE Controller

Product Overview

The TPS2388RTQT is a highly integrated, 4-channel Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller from Texas Instruments. It is designed to deliver up to 30W per port (IEEE 802.3at Type 2) and supports both 2-pair and 4-pair powering schemes. The device operates from a 3.3V supply and integrates all necessary functions for PoE PSE applications, including detection, classification, current limiting, and disconnect detection. Housed in a compact 56-pin QFN (8x8 mm) package, it is ideal for space-constrained networking equipment.
