Maxim's MAX5922, claimed to be the industry's first fully integrated IEEE802.3af-compliant 48 V power switch for power-over-Ethernet (LAN) systems, helps simplify design while reducing external component count and board space. The MAX5922 is used in IEEE802.3af compliant network switches and routers, or midspan power-insertion units that deliver power to network ports. This device allows IP phones, wireless LAN access nodes, and IP security cameras to be remotely powered over the network without causing glitches on the system power-supply rail. Before applying power to a device (load), the MAX5922 detects the presence of a valid 25 kΩ discovery signature and one of the valid IEEE802.3af classification characteristics. An internal 0,45 Ω power MOSFET limits the inrush current during start-up. After start-up, the device provides short-circuit protection. Other features include input undervoltage lockout (UVLO), thermal shutdown, and zero-current load disconnect. Error flags asserted low to monitor faults: UVLO, power-not-good, zero-current detection, and thermal shutdown.
