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 PoE applications. They support IEEE 802.3af, IEEE 802at, HDBaseT, 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 DCDC 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, HDBaseT, and other 2-pair or 4-pair configurations PD detection and programmable classification 2, 3, 4, and 6 event classification Integrated 0.3 isolating (series-pass) FET In-rush current limiting Wall adapter priority support (PD70210A and PD70210AL only) Less than 5 A offset current during detection DFN-16/QFN-38 package Power Good Flag (PD70210 only) Datasheet DS00003695B-page 1 2021 Microchip Technology Inc. and its subsidiaries PD70210/PD70210A/PD70210AL The following table lists the Microchip PD products offerings.
