MAX5972A IEEE 802.3af/at-Compliant Powered Device Interface Controller

The MAX5972A provides a complete interface for a powered device (PD) to comply with the IEEE® 802.3af/ at standard in a power-over-Ethernet (PoE) system. The MAX5972A provides the PD with a detection signature, classification signature, and an integrated isolation power switch with inrush current co.

MAX5972A Features

* an input UVLO with wide hysteresis and long deglitch time to compensate for twisted-pair cable resistive drop and to assure glitch-free transition during power-on/-off conditions. The MAX5972A can withstand up to 100V at the input. The MAX5972A supports a 2-event classification method as specified i
