PD70211ILQ-TR Power Management ICs - PMIC by Microchip Technology
IEEE 802.3at / PoH PD front-end and PWM controller IC w/internal 0.3 Ohm FET
| Status: | Active |
|---|---|
| Series: | PD70211 |
| RoHS: | Compliant |
PD70211 is an advanced Powered Device (PD) Interface IC with integrated switching (PWM) regulator control for PDs in PoE applications. It supports IEEE 802.3af, IEEE 802at, HDBaseT and general 2/4-pair configurations. The PD70211 front-end 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 receives power and generates appropriate flags. The IC features an internal bleeder for discharging the input capacitor of the DC/DC converter rapidly, to ensure fast re-detection and port power-up in case of sudden removal and re-insertion of the Ethernet cable into the RJ-45. The advanced PWM current mode section supports synchronous flyback and active clamp forward topologies, as well as buck, boost etc.
