TPS2377PW TI PoE PD Controller | 8-TSSOP | IEEE 802.3af, 15W

Product Overview

The TPS2377PW 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 a PD to detect, classify, and draw power from a Power Sourcing Equipment (PSE) over Ethernet cables. The device integrates a 0.3-Ω, 100-V, low-side switch with current limiting and thermal protection, ensuring robust operation. Housed in a compact 8-pin TSSOP package, the TPS2377PW simplifies PoE PD design while offering high efficiency and reliability.
