Hi there

I am using DRV8834 IC driver to run the 5v stepper motor using a microcontroller. I've managed to run the 5v stepper motor using DRV8834 IC. But I've found we need 3 pins (Step, Direction and enable) to enable the device and run.

The requirement is to reduce the pins to 2 (only for step and direction). If I don't use the enable pin then the driver and motor consume tiny power. Is there any idea you can help me with to use any MOSFET/any other idea/pulse stretcher to control the power consumption without using the enable pin? Please let me know if you guys got an idea. Your help is much appreciated.

Thanks in advance.

You can permanently pull the enable pin to the enable voltage (high/low) with a 1k resistor.
