Front End PD Interface Controller 16-Pin DFN T/R

PD70210 is an advanced PD Interface Controller (Front-end IC) for Powered Devices in PoE applications. It supports IEEE802.3af, IEEE802at, HDBaseT, and general 2/4-pair configurations. 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 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-detection and port power-up in case of sudden removal and re-insertion of Ethernet cable into RJ-45.

• Supports IEEE802.3af/at, HDBaseT, and other 2-pair/4-pair configurations.
• PD detection & programmable classification
• 2,3,4, and 6 event classification
• Integrated 0.3O isolating (series-pass) FET
• Inrush current limiting
• Less than 5µA offset current during detection
• Lead-free DFN-16 / QFN-38 package
