MAX5972A 19-4924 Rev 1 2/10 IEEE 802.3af/at-Compliant, Powered Device Interface Controller with Integrated Power MOSFET General Description Features S IEEE 802.3af/at Compliant The MAX5972A provides a complete interface for a powered device (PD) to comply with the IEEE 802.3af/ S 2-Event Classification or an External Wall Adapter at standard in a power-over-Ethernet (PoE) system. The Indicator Output MAX5972A provides the PD with a detection signature, S Simplified Wall Adapter Interface classification signature, and an integrated isolation S PoE Classification 0 to 5 power switch with inrush current control. During the inrush period, the MAX5972A limits the current to less S 100V Input Absolute Maximum Rating than 180mA before switching to the higher current limit S Inrush Current Limit of 180mA Maximum (720mA to 880mA) when the isolation power MOSFET S Current Limit During Normal Operation Between is fully enhanced.

For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied.
