IEEE 802.3af/at-Compliant, Powered Device Interface Controllers With Integrated Power MOSFET

The MAX5972A MAX5972B provide 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 MAX5972B provide the PD with a detection signature, classification signature, and an integrated isolation power Switch with inrush current control. During the inrush period, the MAX5972A MAX5972B limit the current to less than 180mA before switching to the higher current limit (720mA to 880mA) when the isolation Power MOSFET is fully enhanced. The devices feature 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 MAX5972B CAN withstand up to 100V at the input. By Maxim Integrated Products
