Microchip Technology, Inc. IEEE 802.3at / PoH PD front-end IC w/internal 0.3 Ohm FET PD70210A

The PD70210A device is an advanced PD interface controller (front-end IC) for powered devices in PoE applications. It supports IEEE 802.3af, IEEE 802at, HDBaseT, and general 2- pair or 4-pair configurations. The PD70210 device includes an advanced classification block that supports 2, 3, 4, and 6 event classification. Using the SUPP_Sx pins, they also identify which of the four pairs of the cable receive power and generates appropriate flags. The IC features an internal bleeder for rapidly discharging the input capacitor of the DC–DC converter, to ensure fast re-detection and port power-up in case of sudden removal and re-insertion of the Ethernet cable into RJ-45.
