Hi Team,
When DRV8300 High-side gate and Low-side driver output MOSFET short ground, what protection mode will be activated?
and what would happen if there was no protection?
For example, half-wave output, or the High-side gate and Low-side driver are short-circuited and burned, or the bootstrap capacitor cannot be charged, etc.
Hi Kevin,
I took a look at your concerns and it looks like DRV8300 only has two protection features:
It is one of our more simple devices, if you are looking for something that has close to the same specifications but more features I would recommend DRV835x
If there is no protection above, please describe what will happen.
For example, half-wave output, or the High-side gate and Low-side driver are short-circuited and burned, or the bootstrap capacitor cannot be charged let high-side mosfet abnormal action, etc.
I can't say for certain what would happen in the event of the shorts the you are seeing but it could potentially cause abs max violations and damage the device or the MOSFETs.
Regards,
Yara
