MAX5981A Overview
The MAX5981 provides a plete interface for a powered device (PD) to ply with the IEEE® 802.3af/at standard in a power-over-ethernet (PoE) system. The MAX5981 provides the PD with a detection signature, classification signature, and an integrated isolation power switch with inrush current control. During the inrush period, the MAX5981 limits the current to less than 180mA before switching to the higher current...
