Maxim Integrated MAX5996 IEEE® 802.3bt-Compliant Powered Device complies with the IEEE 802.3af/at/bt standard in a Power-Over-Ethernet (PoE) system with a detection signature, classification signature, and an integrated power switch with startup inrush current control. The MAX5996 limits the current to 135mA during the startup period, and it switches to a higher current limit when the power MOSFET is fully enhanced. The devices feature a Multi-Event classification, Intelligent MPS, Autoclass, and an input UVLO with wide hysteresis and deglitch time to assure glitch-free transition during power-on/off. The MAX5996 withstands a maximum voltage of 100V at the input.
