TPS2376DDA-H Description

Short technical summary and product information.

The Texas Instruments TPS2376DDA-H is an 8-pin integrated circuit designed to develop high-power IEEE 802.3af style powered devices (PD). This PoE controller offers a higher current limit and increased thermal dissipation capability compared to other devices in its family.

 

Key electrical specifications include a maximum input voltage of 57V and a minimum PoE current limit of 625mA. It supports PD power levels of 13W and 25W, with DC/DC control for PD only operation. The device features programmable inrush limiting, a typical rDS(on) per FET of 580mΩ, and integrated protection features like programmable UVLO and thermal shutdown. Fault response is managed through an auto-retry mechanism.

 

Packaged in an 8-SO PowerPad (8-PowerSOIC) surface-mount package, the TPS2376DDA-H operates within an industrial temperature range of -40°C to 85°C. It includes an integrated 0.58-Ω, 100-V, low-side switch and is capable of handling 15-kV system-level ESD. The device also offers adjustable turn-on thresholds, enabling high-power 26W designs.

 

This component is suitable for applications requiring Power over Ethernet connectivity, providing a robust solution for powering devices through network cables.
