The EVQ6615-QK-00A is an H-bridge dc motor driver evaluation board featuring the MPQ6615-AEC1 IC, which operates from an input voltage of up to 40 V. 

The H-bridge consists of four N-channel power MOSFETs. An internal charge pump generates the gate driver supply voltages for the high-side MOSFETs, and a trickle charge circuit maintains sufficient gate driver voltages for 100% duty cycle operation.

The current flowing through the two Sx outputs is sensed via the internal current-sensing circuits. Each phase has an Output pin which sources or sinks a current proportional to each phase’s output current. Only the current flowing through the low-side MOSFET is sensed. This current is sensed in both the forward and reverse directions.

Internal safety features include over-current protection, under-voltage lockout protection, and thermal shutdown. The input control signals for the MPQ6615-AEC1 are applied through the connector on the board.

The MPQ6615-AEC1 can be used to drive brushed dc motors, door lock and latch motors, and seat actuators.
