TPS2388 Description

Short technical summary and product information.

The Texas Instruments TPS2388 is an 8-channel Power Sourcing Equipment (PSE) controller engineered to insert power onto Ethernet cables according to the IEEE 802.3at standard. This device is fully compliant with IEEE 802.3at, supporting both Type 1 and Type 2 Powered Device (PD) classification.

 

Key electrical features include a maximum input voltage of 57V and a minimum of 44V. The controller offers 8 ports, 2-pair control, and a programmable current limit with foldback for enhanced protection. It provides 14-bit port current and voltage monitoring with 100-ms rolling averaging and 2% current sensing accuracy. A 0.255-Ω sense resistor with Kelvin sense is utilized.

 

The TPS2388 operates across a wide temperature range of -40°C to 125°C. It communicates via I2C and includes an I2C watchdog for failsafe operation. The device is available in a 56-lead VQFN package measuring 8mm x 8mm.

 

Applications for the TPS2388 include enterprise and SoHo switches and routers, PoE pass-through power modules, and Network Video Recorders (NVRs). Its external FET architecture allows designers to balance size, efficiency, thermal, and cost requirements.
