IEEE 802.3af PD Interface Controller For Power-Over-Ethernet
MAX5940A/MAX5940B/MAX5940C/MAX5940D
General Description
The MAX5940A/MAX5940B/MAX5940C/MAX5940D provide plete interface function for a powered device (PD) to ply 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. These devices also feature power-mode undervoltage lockout (UVLO) with wide hysteresis and powergood outputs. The MAX5940A/MAX5940B are available with an...
