The PD70210 device is an advanced Powered Device (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 actually receive power and generates appropriate flags. The IC features an internal bleeder for rapidly discharging the input capacitor of the DC–DC converter, so as to ensure fast re-detection and port power-up in case of sudden removal and re-insertion of the Ethernet cable into RJ-45.
Start your PoE PD power supply design using Microchip MPLAB® Analog Designer.
Additional Features
Supports IEEE 802.3af/at, HDBaseT, with 2-pair or 4-pair configurations
