TPS23851DCE Description

Short technical summary and product information.

The Texas Instruments TPS23851DCE is a quad-channel Power Sourcing Equipment (PSE) controller designed for inserting power onto Ethernet cables according to IEEE 802.3at and 802.3af standards.

 

This controller features four independent PSE ports, supporting PD detection and classification, and providing current limit output protection. It operates with a supply voltage range of 44V to 57V and a maximum power dissipation of 34.2W. The device is specified for an operating temperature range of -20°C to 85°C.

 

The TPS23851DCE is housed in a 36-SSOP package, with a surface mount type. It supports industry-standard register sets for software compatibility and offers flexible operation modes, including automatic and semi-automatic port control.

 

Key electrical characteristics include a supply current of 2mA and support for both 802.3at (PoE+) and 802.3af (PoE) standards. The controller is designed for applications such as Ethernet switches and routers requiring Power over Ethernet capabilities.
