3af/at-Compliant, Powered Device Interface Controller with Integrated Power MOSFET General 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.
The MAX5972A provides the PD with a detection signature, classification signature, and an integrated isolation power switch with inrush current control.
During the inrush period, the MAX5972A limits 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 device featu...
