MP6507 2.7-15V, 700mA Bipolar Stepper-Motor Driver TSSOP16

The MPS MP6507 is a Bipolar Stepper-Motor Driver. It operates from a 2.7 V to 15 V input and is rated for 700 mA. It is supplied in a TSSOP16 package.

The MP6507 is a bipolar stepper-motor driver with dual, built-in full-bridges consisting of N- channel power MOSFETs.

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.
