The Texas Instruments TPS2388RTQR is an 8-channel Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller designed for PoE applications. It fully complies with IEEE 802.3at standards, supporting both Type 1 (802.3af) and Type 2 PoE.
Key electrical features include an input voltage range of 44V to 57V, 2-pair control, and programmable current limit with foldback. The device offers advanced features such as fast port shutdown, port re-mapping, multi-level port priority, and over-current/over-temperature reporting. It provides 14-bit port current and voltage monitoring with 100-ms rolling averaging and 2% current sensing accuracy. Communication is handled via I2C, which also includes a watchdog for failsafe operation.
This controller operates within a temperature range of -40°C to 125°C. It is housed in a 56-lead VQFN (8x8 mm) package and is designed for surface mount applications. The TPS2388RTQR is suitable for implementing robust and efficient PoE power sourcing solutions in network equipment, access points, and other powered devices.
