MAX5940B Overview
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.
Key Features
- power-mode undervoltage lockout (UVLO) with wide hysteresis and powergood outputs
- An integrated MOSFET provides PD isolation during detection and classification
- All devices guarantee a leakage current offset of less than 10µA during the detection phase
- A programmable current limit prevents hig
