MAX5995B Datasheet Powered Device Interface Controllers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: EVALUATION KIT AVAILABLE Click here for production status of specific part numbers. MAX5995A/B/C IEEE 802.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX5995A/MAX5995B/MAX5995C provide a plete interface for a powered device (PD) to ply 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.
