Which motor driver to choose?

Other Parts Discussed in Thread: DRV8231A

I am trying to find the right motor driver for my project:

Two equal motors, brushed, 24V 0,5A to run, 2-3A to start, only running one at a time.

“Soft start”, so a motor does not draw more than 1A.

On/off control from ESP32.

Current feedback to ADC, to see if the motor is pulling heavier.

Fault feedback.

    Hi Egil,

    The DRV8231A will be the best solution. This driver is a single BDC motor driver with integrated H-bridge and current sensing for limiting the current during motor startup. In your case, you'll need two motor drivers, one for each motor. The DRV8231A has a dedicated pin (IPROPI) that provides a voltage proportional to the motor current. The IPROPI pin can be connected directly to an ADC to monitor the motor current.
