MAX5995B Overview
Description
The MAX5995A/MAX5995B/MAX5995C provide a complete interface for a powered device (PD) to comply with the IEEE® 802.3af/at/bt standard in a Power-Over-Ethernet (PoE) system. The devices provide the PD with a detection signature, classification signature, and an integrated isolation power switch with startup inrush current control.
Key Features
- The devices can withstand a maximum voltage of 100V at the input
- The devices also provide a power-good (PG) signal, twostep current limit and foldback control, overtemperature protection
- An Ultra-Low-Power sleep mode feature in the MAX5995A/MAX5995B further reduces power consumption while still generating MPS current
- The MAX5995B/MAX5995C provides Intelligent Maintain Power Signature (IMPS) feature to automatically enable MPS current by detecting the
