MPQ6612A-D-AEC1 4-40V, 5A H-Bridge DC Motor Driver QFN-18
The MPS MPQ6612A-D-AEC1 is a H-Bridge DC Motor Driver. It operates from a 4 V to 40 V input and is rated for 5 A. It is supplied in a QFN-18 package. The part is AEC-Q100 qualified.
The MPQ6612A and MPQ6612A-D are H-bridge motor drivers used for driving reversible motors, which can drive one DC motor, one winding of a stepper motor, or other loads.

Design Notes
- Set dead time to match the external FET turn-off, not the datasheet typical. Too little risks shoot-through, too much distorts the current waveform at low duty cycle.
- Use a Kelvin connection for the current-sense resistor; shared copper injects switching noise straight into the sense amplifier.
- The thermal pad is the only heat path for most packages — via-stitch it to a ground plane with at least 9 vias.
- PWM frequency trades switching loss against current ripple in the motor inductance; 20 kHz keeps the drive out of the audible band.
- Add a brake or coast path so regeneration during a fast stop does not pump the supply rail.
