MC33926 Motor Driver Carrier
This breakout board for Freescale’s MC33926 full H-bridge has an operating range of 5 V to 28 V and can deliver almost 3 A continuously (5 A peak) to a DC motor. The MC33926 works with 3 V to 5 V logic levels, supports ultrasonic (up to 20 kHz) PWM, and features current feedback, under-voltage protection, over-current protection, and over-temperature protection.

Notes:
- 1
- Without included hardware.
- 2
- Operation from 5 V to 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.
