Hi there

I am using DRV8834 IC driver to run the 5v stepper motor. 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.

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.
