DRV11873: problem

Part Number:DRV11873

Hi team,

I have some problem when using DRV11873, sometimes DRV11873 can not drive the BLDC, unless power on again.

when this fault happens, RD goes high, and CPN goes low, why does this fault happened?

Is RD pin high means lockout protection? And what is the cause of lockout protection?

Thanks!
