TPS23851DCE TI Power Management IC | 36-SSOP | PoE PSE Controller, 4-Channel

Product Overview

The TPS23851DCE from Texas Instruments is a highly integrated, 4-channel Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller. 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. Housed in a compact 36-SSOP package, this device simplifies the design of midspans, switches, and other PoE-enabled networking equipment.
