Hi,
Here's my schematic, And when I set the grid drive to 150/300mA , 24V short circuit test (two half-bridge mid-point short connection) will damage DRV8701, directly A phenomenon that nFAULT pin outputs low levels, And DRV8701 a short circuit inside, Chip damage. But 12 V doesn't damage when it's powered. Then I took IDRIVE pin directly to AVDD, Close OCP protection, Driving capacity 25/50mA, At this point, the same short circuit test as above will find no problem, The chip can also be protected normally. So is this a problem OCP protection? Or is there a problem with my schematic design?I hope you can answer my question!
