PD70210/PD70210A/

PD70210AL

Front-End PD Interface Controller

Product Overview

The PD70210, PD70210A, and PD70210AL devices are advanced PD interface controllers (front-end IC) for powered

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.
