Product details

Description

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.

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 in the IEEE 802.3at standard and provides a signal to indicate when probed by Type 2 power-sourcing equipment (PSE). The device detects the presence of a wall adapter power-source connection and allows.
