Part Number:DRV8873
Hi all !
I'm currently designing a motor driver and I bought a DRV8873, SPI version, thinking I could write a value to some register and tell it to output a PWM wave with that value's duty cycle.
Upon testing it I realized I can only enable or disable IN1/IN2 bits, such as I would have if I had driven the equivalent pins at +VM/GND without PWM ; this gives me the possibility to drive the motor at full speed forward, reverse, brake or coast over SPI.
I would like to know if it is possible to drive a motor using a DRV8873 (SPI version) with a duty cycle without actually using the IN1/IN2 pins or sending a PWM to the driver.
If it is not, could you recommend an alternative ?
Many thanks in advance for your help !
