MP6513 2.5-21V, 0.8A H-Bridge Motor Driver in a TSOT23-6

The MPS MP6513 is a H-Bridge Motor Driver in a TSOT23-6. It operates from a 2.5 V to 21 V input and is rated for 0.8 A. It is supplied in a TSOT23 package.

The MP6513 is an H-bridge motor driver 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.
