DRV8889-Q1: The output signal can still be detected on the A2 pin after the pwm signal on the step pin is disconnected

Hi team,

When using the DRV8889-Q1, the motor can stop spinning when the pwm signal at the step pin is stopped, but the output signal can still be detected at the A2 pin with the motor heating up. 

Could you help check this case? Thanks.

Best Regards,
