The POE MQ7804M series of modules are designed to extract power from a conventional twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3af/at Power-over-Ethernet (PoE) standard but with 50W output power. The MQ7804M have two pairs of power inputs pins: - VA1&2 and VB1&2 to accommodate two PoE options.

The MQ7804M signature and control circuit provides the PoE AT compatibility signature and power classification required by the Power Sourcing Equipment (PSE) before applying up to power to the port. The MQ7804M is preset to Class 5 and MQ7804M-1 is preset to Class 4.

The high efficiency DC/DC converter operates over a wide input voltage range and provides a regulated low ripple and low noise output. The DC/DC converter also has built-in overload and short-circuit output protection.
