DRV8312: DRV8312

noam yinon

Part Number: DRV8312

I have a few questions regarding the recording attached

1. Is situation that RESET ,A,B,C are high can cause damage to DRV8312 even when the PWM lines are low

2. this is my PWM signal (the motor rotate) is this situation normal when PWM A,B are simultaneously high, or could it cause damage to DRV8312

because this situation differs from the PWM in the data sheet - PWM A inverted from PWM B

best regars

Hi Noam,

It is difficult to speculate if this scenario would cause damage. Have you seen damage under these conditions?

If you have, what have you observed at the outputs of the device?
