The POE MQ7804BS series of modules are designed to extract power from a conventional twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3bt Power-over-Ethernet (PoE) standard but with 72W output power. The MQ7804BS series of modules embedded 2 active rectifier bridges which extremely reduce the power dispassion comparing with the traditional Schottky diodes bridges, have two pairs of power inputs pins: - VA1&2 and VB1&2 to accommodate high power PoE application with 4-pair wire power transfer.   

      The MQ7804BS signature and control circuit provides the PoE bt compatibility signature and power classification required by the Power Sourcing Equipment (PSE) before applying up to power to the port. The MQ7804BS can be set to class4 to class 8 by external one classification resistor to get different power class from PSE.   

      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.
