hello,
My customer used the DRV8305 to develop the motor control board, now we met the issue is dead-time is not stable of DRV8305, The dead-time configured as 0.5us. but some time, there is no dead-time of DRV8305 output, and the HS and LS occur short in minute time.
Do you know why, and any comments for it? thanks very much!
the waveform as below:
1. correct waveform as picture one(purple and green line are the PWM input of DRV8305; yellow and blue are the PWM output of DRV8305 )
2. incorrect waveform as picture two(purple and green line are the PWM input of DRV8305; yellow and blue are the PWM output of DRV8305 )
