TPS23861PW Description

Short technical summary and product information.

The Texas Instruments TPS23861PW is an integrated circuit designed for Power over Ethernet (PoE) Power Sourcing Equipment (PSE) applications. This 4-channel controller supports both IEEE 802.3at Type 1 (802.3af) and Type 2 standards, enabling efficient power delivery over Ethernet cables.

 

Key electrical specifications include an input voltage range of 44V to 57V and a power output capability of 25.5W. The device operates with a current draw of 3.5mA and features a type of Controller (PSE). It is housed in a 28-TSSOP package, suitable for surface mount applications.

 

The TPS23861PW operates within a temperature range of -40°C to 125°C. Its design includes features for autonomous mode operation, current limiting with foldback, fast shutdown, and reporting for over-current and over-temperature conditions. The controller is designed for efficient operation with a 255-mΩ sense resistor and supports two-layer PCB Kelvin current sensing.

 

This component is ideal for systems requiring robust PoE power sourcing, such as network switches, industrial control systems, and wireless access point backhaul. The surface mountable 28-TSSOP package facilitates integration into compact designs.
