TPS23851DCER TI Power Over Ethernet Controller | 36-SSOP | 4-Channel, IEEE 802.3at

Product Overview

The TPS23851DCER from Texas Instruments is a highly integrated, 4-channel Power over Ethernet (PoE) controller designed for Power Sourcing Equipment (PSE) in compliance with IEEE 802.3at (PoE+) and IEEE 802.3af standards. It supports up to 30W per port and features advanced power management, including programmable current limits, classification, and disconnect detection. Housed in a compact 36-pin SSOP package, it is ideal for space-constrained applications such as switches, routers, and midspans.
