MAX5940BESA+ - Brand New Maxim Integrated Power Over Ethernet Controllers
-
General Description
The MAX5940A/MAX5940B 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 provide the PD with a detection signature, a classification signature, and an integrated isolation switch with programmable inrush current control. These devices also feature power-mode undervoltage lockout (UVLO) with wide hysteresis, and power-good outputs.
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
♦ Gate Output Allows External Control of the Internal Isolation MOSFET
♦ Programmable Inrush Current Control
♦ Programmable Undervoltage Lockout (MAX5940B 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 RangeApplications
