General Description
The MAX5940A/MAX5940B/MAX5940C/MAX5940D provide complete interface function for a powered device (PD) to comply with the IEEE 802.3af standard in a power-over-ethernet system. MAX5940A/MAX5940B/MAX5940C/MAX5940D provide the PD with a detection signature, a classification signature, and an integrated isolation switch with programmable inrush current control.
Features
? Fully Integrated IEEE 802.3af-Compliant PD Interface
? PD Detection and Programmable Classification Signatures
? Less than 10μA Leakage Current Offset During Detection
? Integrated MOSFET For Isolation and Inrush Current Limiting
? 90V Absolute Maximum Rating (MAX5940C/MAX5940D)
? Gate Output Allows External Control of the Internal Isolation MOSFET
? Programmable Inrush Current Control
? Programmable Undervoltage Lockout (MAX5940B/MAX5940D Only)
? Wide UVLO Hysteresis Accommodates TwistedPair Cable Voltage Drop
? PGOOD/PGOOD Outputs to Enable Downstream DC-DC Converters
? -40°C to +85°C Operating Temperature Range
Applications
??? IP Phones
??? Security Cameras
??? Wireless Access Nodes
??? IEEE 802.3af Power Devices
??? Computer Telephony
