This dual brushed DC motor driver, based on Freescale’s MC33926 full H-bridge, has a wide operating range of 5 – 28 V and can deliver almost 3 A continuously (5 A peak) to each of its two motor channels. The MC33926 works with 3 – 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 - 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
On motor voltage only; logic voltage does not have reverse protection.
