TPS23785BPWPR Description

Short technical summary and product information.

The Texas Instruments TPS23785BPWPR is a combined Power over Ethernet (PoE) powered device (PD) interface and current-mode DC-to-DC controller. It is optimized for non-isolated converters and supports high-efficiency topologies.

 

This controller adheres to PoE standards including 802.3at Type 1 (802.3af) and 802.3at Type 2, with PD power levels of 13W and 25W. It features a wide input voltage range from 15.7V to 57V, a minimum PoE current limit of 850mA, and a typical inrush limit of 0.14A. The integrated hotswap MOSFET is rated for 100V and has an rDS(on) of 0.5Ω, with a typical per-FET rDS(on) of 430mΩ.

 

Designed for robust operation, the TPS23785BPWPR includes features such as thermal shutdown and auto-retry fault response. It operates across a wide temperature range of -40°C to 125°C (junction temperature).

 

The device is available in a 24-HTSSOP package, suitable for surface mounting. Its functionality as both a PoE interface and a DC-to-DC controller makes it a versatile component for power sourcing equipment.
