Product Overview

The TPS2377DR-1 from Texas Instruments is a highly integrated Power over Ethernet (PoE) Powered Device (PD) controller designed for IEEE 802.3af applications. It provides a complete interface for PDs to detect, classify, and draw power from Power Sourcing Equipment (PSE) over Ethernet cables. The device integrates a 0.3-Ω, 100-V power MOSFET, making it ideal for high-efficiency designs. Housed in an 8-SOIC package, it offers a compact solution for space-constrained applications.
