TPS23881ARTQR TI Power Management IC | 56-VQFN (8X8) | 4-Pair PoE PSE, IEEE 802.3bt

Product Overview

The TPS23881ARTQR is a highly integrated, quad-port, 4-pair Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller from Texas Instruments. It complies with IEEE 802.3bt (Type 3 and Type 4) standards, delivering up to 90W per port. The device simplifies PoE system design by integrating detection, classification, current limiting, and disconnect detection. It operates from a 3.3V supply and supports both 2-pair and 4-pair powering modes. The 56-VQFN (8x8) package enables compact PCB layouts for space-constrained applications.
