TPS2388RTQR TI Power Management IC | 56-QFN (8x8) | 8-Channel PoE PSE Controller

Product Overview

The TPS2388RTQR is a highly integrated, 8-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) or 15.4W per port (IEEE 802.3af Type 1) over 4-pair or 2-pair Ethernet cables. Housed in a compact 56-pin QFN (8x8 mm) package, this device simplifies the design of midspans, switches, and routers by integrating detection, classification, current limiting, and disconnect sensing functions.
