DRV8353: DRV8353 - Damaged after freerun when stop PWM

Part Number: DRV8353

Dear all,

I test with an DRV8353 Evaluation Kit an an BLDC in freerun at 18V and approx. 6A nominal current in free run. The free run ist good. But if I stop the PWM Signal to the DRV8353 the Motor stop rotating immediately. After two or three times the DRV8353 is damaged. If I start PWM signal the fault LED is on and the motor don't start moving. It is a bad solution to stop PWM immediately?

I hope you understand. If you need more information I try to give it to you!

Thank you!
