MAX5922 - +48V / Single-Port Network Power Switch

MAX5922 Description

19-2708; Rev 0; 4/03 +48V, Single-Port Network Power Switch For Power-Over-LAN General .
The MAX5922A/B/C is a single-port network power controller with an integrated power MOSFET, operating from a +32V to +60V supply rail.

MAX5922 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 li

MAX5922 Applications

* and is fully compliant 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 compliant PSE. The MAX5922 is suitable for PSE function in both switch/router systems where the power is delivered
