Are there any such high current motor drivers available that are compatible with 5V logic input supply?

Thank You

Vineet,

If your application requires a brushed DC or stepper motor, the DRV8412 (6A max) or DRV8432 (12A max) can be run off of 5 V. If you are spinning a brushless DC motor, the DRV8312 (6.5A max) or DRV8332 (13A max) will work.

Matt,

Thanks for you reply. But in the absolute maximum ratings as given in the the datasheet of DRV8412 and others, the difference between PWM_X and GND is specified to lie in between -0.3 to 4.2V. I want to use it with an Arduino.

And i'll be operating the motor driver using arduino at low frequencies like 500hz, 1kHz or 3.6kHz maximum. Will there be problems in this case?

Vineet,

The DRV8840 is about the highest current integrated driver we have that meets your needs of 5V logic inputs.

Alternatively, you could use the DRV8301 + external FETs to create a very high curent (evaluation board is up to 82A) DC motor driver.
