I’ve read the schematics of drv8301. And find out the spi signals are isolated.
Why should do these ? Does the high-voltage power supply PVDD will affect the control spi signal ?
(And I know that ,the spi signals are not directly connect to the drv8301, but it’s not important.)
And, in my case, I’ll use FPGA to provide the PWM signals, then use the PWM to drive the DRV8301.
Is here should be isolated with FPGA (PWM) and DRV8301 ?
