Manufacturer: Maxim Integrated (now Analog Devices)

Overview: Click here for production status of specific part numbers. MAX5982A/MAX5982B/ MAX5982C EVALUATION KIT AVAILABLE IEEE 802.

General Description

The MAX5982A/MAX5982B/MAX5982C provide 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 MAX5982A/MAX5982B/MAX5982C provide the PD with a detection signature, classification signature, and an integrated isolation power switch with inrush current control.

During the inrush period, the MAX5982A/MAX5982B/MAX5982C limit the current to less than 182mA before switching to the higher current limit (1700mA to 2100mA) when the isolation power MOSFET is fully enhanced.
