[FAQ] What is the use of T2P in PoE applications?

Hardware classification allows a PSE to determine a PD’s power requirements before powering, and helps with power management once power is applied. Type 2 hardware classification permits high power PSEs and PDs to determine whether the connected device can support high-power operation. TI’s PoE PD devices can process hard classification and output T2P Low.
