TPS23841PJD TI Power Management IC | 64-HTQFP (10x10) | 4-Channel, IEEE 802.3at PoE

Product Overview

The TPS23841PJD is a highly integrated, 4-channel Power over Ethernet (PoE) controller from Texas Instruments. It is designed to comply with IEEE 802.3at (PoE+) standard, delivering up to 30W per port. The device integrates detection, classification, current limiting, and disconnect detection, making it ideal for midspan and endpoint PSE applications. Packaged in a compact 64-HTQFP (10x10 mm), it offers a robust solution for space-constrained designs.
