PD70211
PD Controller with Switching
Regulator for AF/AT/UPOE/HDBaseT/4-pair PoE Applications
f Description
PD70211 is an advanced PD Interface IC with integrated switching (PWM)
regulator control for Powered Devices in PoE applications.
It supports IEEE802.
3af, IEEE802at, HDBaseT and general 2/4-pair configurations.
The PD70211 front-end 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 actually receives 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-...
