MAX5995A/B/C IEEE 802.3bt-Compliant, Powered Device Interface Controllers with Integrated 91W High-Power MOSFET General Description The MAX5995A/MAX5995B/MAX5995C provide a complete interface for a powered device (PD) to comply with the IEEE® 802.3af/at/bt standard in a Power-Over-Ethernet (PoE) system. The devices provide the PD with a detection signature, classification signature, and an integrated isolation power switch with startup inrush current control. During the startup period, the devices limit the current to 135mA (typ) before switching to the higher current limit (1800mA to 2400mA, typ) when the isolation power MOSFET is fully enhanced.
