TPS23841PAPR TI Power Over Ethernet Controller | 64-HTQFP (10x10) | 4-Channel, IEEE 802.3at

Product Overview

The TPS23841PAPR from Texas Instruments is a quad-channel Power over Ethernet (PoE) controller designed for Power Sourcing Equipment (PSE) applications. It fully complies with IEEE 802.3at (PoE+) standards, delivering up to 30W per port. Housed in a compact 64-pin HTQFP (10x10 mm) package, it integrates detection, classification, current limiting, and fault protection for four independent Ethernet ports. The device supports both Auto and Semi-Auto modes, enabling flexible power management. With its robust feature set, the TPS23841PAPR is ideal for enterprise switches, industrial Ethernet, and wireless access points.
