DRV8328: DRV8328A Some Units Won't Spin With Complementary PWM Off

Part Number: DRV8328

Tool/software:

I have a DRV8328A design that is working well with complementary PWM on. About 1/3 of the units are unable to spin a motor with complementary pwm turned off.

I have played around with the gate resistors and bootstrap capacitor values to with no change.

    Hi Alex,

    Can you clarify what you mean by complimentary signals? From my understanding this device doesn't have an "inverted" variant so your high and low PWM signals would almost always have to be complimentary correct? What PWM mode are you using? 

    Regards,
