TPS2383PMR

Overview

The TPS2383PMR is an octal Power Sourcing Equipment (PSE) power manager manufactured by Texas Instruments. Designed for IEEE 802.3af compliant systems, this component manages up to eight independent PoE channels within a single integrated circuit. It operates with a supply voltage range of 44V to 57V and supports a maximum power output of 15.4W per channel. The device is housed in a 64-pin LQFP package measuring 10x10 mm, suitable for surface mount applications. It functions as a central controller for distributing power over Ethernet networks while ensuring compliance with safety and performance standards.
