Overview
The TPS2376DDAR-H is a Power over Ethernet (PoE) controller from Texas Instruments, designed to support high-power IEEE 802.3af compliant powered devices (PDs). This integrated circuit is part of the TPS2376-H family and is optimized for high-power applications, offering enhanced current limits and thermal dissipation capabilities. It is particularly suited for developing PDs that require more power than standard implementations, such as those drawing up to 26 W from a 52-V power sourcing equipment (PSE) over 100 meters of CAT-5 cable.
