TPS2377DR TI PoE PD Controller | 8-SOIC | 0V-57V, IEEE 802.3af

Product Overview

The TPS2377DR from Texas Instruments is a Power over Ethernet (PoE) Powered Device (PD) controller designed for IEEE 802.3af compliant applications. It integrates a 0.3-Ω, 100-V, N-channel MOSFET and provides a complete PD interface, including detection, classification, and power switching. The device operates over a wide input voltage range of 0 V to 57 V and delivers up to 15.4 W to the load. Housed in an 8-pin SOIC package, the TPS2377DR is ideal for space-constrained applications requiring efficient power conversion and robust protection features.
