MAX5922 Datasheet +48v / Single-port Network Power Switch

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-2708; Rev 0; 4/03 +48V, Single-Port Network Power Switch For.

General Description

The MAX5922A/B/C is a single-port network power controller with an integrated power MOSFET, operating from a +32V to +60V supply rail.

The device is specifically designed for power-sourcing equipment (PSE) in powerover-LAN applications and is fully pliant to the IEEE 802.3af standard.

The MAX5922 provides power devices (PD) discovery, classification, current limit, and other necessary functions for an IEEE 802.3af pliant PSE.

Key Features

  • a programmable undervoltage lockout (UVLO) that keeps the device in shutdown until the input voltage exceeds a certain threshold, set to 38V (MAX5922A) or 28V (MAX5922B/C) internally. After successfully discovering and classifying a PD, the MAX5922 enters startup mode. During startup, the MAX5922 limits the output voltage and current slew rate to minimize EMI (electromagnetic interference). The MAX5922 has an integrated 0.45Ω N-channel power MOSFET that provides efficient operation and simplifie.
