DRV8301: Power Control

Other Parts Discussed in Thread: DRV8301

Hi,

i want to use a DRV8301 for a BLDC (3Phase) application (The Power Level is up to a few kW).

I also want to control the power by a uC via PWM. Is it possible to control the Power Level by using a PWM module at the Power Source or
should i set the PWM Signal directly on the Input Ports of the DRDRV8301 ?

Thanks!

You should set the PWM signal directly on the input pins of the DRV8301.

Thanks!

Im using digital Hall sensors, can you recommend a motor controller for the PWM-control to me?

I also found the Hercules (Arm Cortex) Microcontroller which seems as a possible solution.
So if i use this solution i can connect the Hercules MCU (PWM Outputs) to the DRV8301 ?
