PoH/PoE+ 2-pairs/4-pairs PD front end.

Product Detail

PoH/PoE+ 2-pairs/4-pairs PD front end. It supports IEEE802.3af, IEEE802at, HDBaseT and general 2/4-pair configurations. The PD70210 includes an advanced classification block that supports 2, 3, 4 and 6 event classification. Using the SUPP_Sx pins, it also identifies which of the four pairs of the cable are actually receiving power and generates appropriate flags. The IC features an internal bleeder for discharging the input capacitor of the DC/DC converter rapidly, so as to ensure fast re-detection and port power-up in case of sudden removal and re-insertion of the Ethernet cable into the RJ-45.
