TPS23881RTQT TI PoE PSE Controller | 56-VQFN (8x8) | 4-Pair, 90W, IEEE 802.3bt

Product Overview

The TPS23881RTQT is a highly integrated, quad-channel Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller from Texas Instruments. It supports IEEE 802.3bt (PoE++) standard, delivering up to 90W per port over 4-pair Ethernet cables. Housed in a compact 56-pin VQFN (8x8 mm) package, it is designed for high-density PoE applications such as switches, routers, and midspans. The device integrates four independent PSE channels with advanced power management, including per-port current sensing, programmable power limits, and support for both 2-pair and 4-pair configurations. With its robust protection features and I2C interface for monitoring and control, the TPS23881RTQT simplifies the design of compliant and efficient PoE systems.
