TPS2376DDA-HG4

The Texas Instruments TPS2376DDA-HG4 is an 8-pin integrated circuit designed for high-power IEEE 802.3af style powered devices (PD). It offers a higher current limit and increased thermal dissipation capability compared to other devices in the TPS237X family.

This PoE controller implements a fully compliant PoE interface while permitting non-standard implementations that draw more power, enabling designs up to 26W when working from a 52V minimum PSE over 100m of CAT-5 cable. Key features include a 100V rating, 600mA capability, adjustable inrush limiting, fault protection with auto-retry, and true open-drain power-good functionality.

The TPS2376DDA-HG4 operates within an industrial temperature range of -40°C to 85°C and comes in an 8-Pin PowerPad SOIC package. It supports PoE standards up to 802.3at Type 1 (802.3af) and can handle PD power levels of 13W and 25W. The device features a minimum PoE current limit of 625mA and a typical rDS(on) per FET of 0.58 Ohms.

Designed for powered devices, the TPS2376DDA-HG4 integrates essential features for PoE applications, including programmable UVLO and thermal shutdown. Its 15-kV system-level ESD capability ensures robustness in various operating environments.
