CCS/DRV8323: update from DRV8305 to DRV8323
Part Number: DRV8323
Tool/software: Code Composer Studio
Hello everyone, I am again with a question on DRV8323.Driver output looks like this
I can not understand where these short signals come from. At the input of the driver, the signal is not interrupted.
Green middle point of the bridge. blue gate high FET.
The output of DRV8305 looks better.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Adam Sidelsky:
I use CSD88599Q5DC. I use DRV8323RH. I tried IDRIVE = Hi-Z 240IDRIVE = 75 kΩ to DVDD 520, IDRIVE = 18 kΩ to DVDD 1140, IDRIVE = to DVDD 2000.
R15,R16 = 0R.
In reply to Andrew Buckin:
The second transistor is not installed.
Switching in one channel is induced on the gate in another channel?Does Switching open a high transistor in another channel and then the driver closes it?
I looked three channels in the gates. In one of the channels visible fluctuations. 0-RPM. IDRIVE - 2A.
We have a standard scheme. :)EVO BLDC 6050C.PDF
