Hello,
I want to use Steval-ihm023v3 as my motor driver and I am using a TI microcontroller. I have two questions:
- Do I need to use opto-couplers to connect PWM pins of the driver to MCU?
- Do I need to have signal conditioning fo reading the currrent of the phases? From the schematics, I can see that the voltage of the shunt resistors are passed through Op-amps, but I want to make sure that this voltage is under 3.3V so that it won't ruin the ADC and MCU.
Regards,
Ata
