19-2708; Rev 0; 4/03 +48V, Single-Port Network Power Switch For Power-Over-LAN 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 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 to the load through the signal pairs, and in midspan systems whe...
