Frequently Asked Questions
What is the maximum power output per port of the TPS23861PWR?
The TPS23861PWR supports IEEE 802.3at (PoE+) standard, delivering up to 30W per port across all four ports simultaneously. It also supports legacy IEEE 802.3af devices at up to 15.4W per port, with automatic classification to detect the attached PD power class.
What supply voltage does the TPS23861PWR require?
The TPS23861PWR operates with a supply voltage of up to 3.6V for the logic and I2C interface domain. The PoE power path typically operates from a 44V–57V DC bus in compliant 802.3at PSE designs. Always refer to the datasheet for complete power sequencing requirements.
What package does the TPS23861PWR come in and is it RoHS compliant?
The TPS23861PWR is available in a 28-pin TSSOP (Thin Shrink Small Outline Package) with 0.65mm pitch, suitable for high-density PCB layouts. It is fully RoHS compliant (Pb-free, JEDEC e4 moisture sensitivity), with a peak reflow temperature rating of 260°C.
Can the TPS23861PWR replace other quad-port PoE controllers?
The TPS23861PWR is a direct functional equivalent for many quad-port IEEE 802.3at PSE controllers with I2C control interfaces. Common alternatives include the LTC4266, PD69104, and similar devices. Pin and register compatibility should be verified against your specific PCB design and firmware before substitution.
