MC33926 Motor Driver Carrier

This breakout board for Freescale MC33926 full H-bridge has an operating range of 5 to 28 V

Delivers almost 3 A continuously (5 A peak) to a DC motor.


The MC33926 works with 3 to 5 V logic levels, supports ultrasonic (up to 20 kHz) PWM,


  • current feedback,

  • under-voltage protection,

  • over-current protection, and

  • over-temperature protection.

1    Without included hardware.
2    Operation from 5 - 8 V reduces maximum current output.
3    The device is protected for transients up to 40 V.
4    Can be improved by addition of heat sink or forced air flow.
5    SLEW pin should be HIGH for frequencies above 10 kHz.
6    Input HIGH threshold can be as high as 2.0 V.
7    On motor voltage only; logic voltage does not have reverse protection.
