The Texas Instruments TPS23881RTQR is an 8-channel Power Sourcing Equipment (PSE) controller designed for advanced Power over Ethernet (PoE) applications. It fully supports IEEE 802.3bt standards, including Type 1 (802.3af), Type 2 (802.3at), Type 3, and Type 4.
This controller features a 57V maximum input voltage and a 44V minimum input voltage, with programmable power limiting accuracy of ±2.5%. It offers 8 independent PSE channels with selectable 2-pair or 4-pair port power allocations, supporting power levels from 15.4W up to 90W. Key features include Auto Mode, Current Limit with Foldback, Fast shutdown, Multi Level Port Priority, Over Current Reporting, and Over Temp Reporting.
The TPS23881RTQR is available in a 56-VQFN (8x8 mm) package and is designed for surface mount installation. It operates within an ambient temperature range of -40°C to 125°C. The device is compatible with TI's FirmPSE system firmware and includes features like legacy PD capacitance measurement and noise-immune MPS for DC disconnect.
This component is suitable for applications requiring robust and flexible PoE power sourcing, such as network switches, access points, and other powered devices that need to deliver power over Ethernet cables.
