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 devices in Po E applications. They support IEEE® 802.3af, IEEE 802at, HDBase T, and general 2-pair or 4-pair 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. Features The following are the Features of PD70210, PD70210A, and PD70210AL devices. - Supports IEEE 802.3af/at, HDBase T, and other 2-pair or 4-pair configurations - PD detection and programmable classification - 2, 3, 4, and 6 event classification - Integrated 0.3 Ω isolating (series-pass) FET - In-rush current limiting - Wall adapter priority support (PD70210A and PD70210AL only) - Less than 5 μA offset current during detection - DFN-16/QFN-38 package - Power Good Flag (PD70210 only) © 2021 Microchip Technology Inc. and its subsidiaries DS00003695B-page 1 PD70210/PD70210A/PD70210AL The following table lists the Microchip PD products offerings.
