MICROCHIP PD70210AILD-TR

The PD70210, PD70210A, and PD70210AL devices are advanced PD interface controllers (front-end IC) for powered devices in PoE applications. They support IEEE 802.3af, IEEE 802at, HDBaseT, and general 2-pair or 4-pair configurations. The PD70210, PD70210A, and PD70210AL devices have an advanced classification block that supports 2, 3, 4, and 6 event classification. These devices also identify the four pairs of cable that receives power and generates appropriate flags by using the SUPP_Sx pins. 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 on sudden removal and re-insertion of the Ethernet cable into RJ45.
