Hi N.AB
Note that you are using high voltage >60V in another post, is that the same case here?
Normally DRV8303 will not die because of over current as it is a pre-driver. But the voltage >60V will be the No.1 killer to the device.
Even you lower the system voltage < 60V but not enough margin included, the motor is most likely to generate VM pumping voltage when it is in the deceleration state.
Also in your schematic, only see 2.2uF to PVDD and all the half bridge top as the bulk cap. This is not enough for most BLDC applications.
Best regards
