Hi,
I'm using a DRV8844 in a configuration where I parallel the outputs to drive a single BDC motor bidirectionally. It had been working fine so several weeks, until we wanted to do some testing on another part of the system that this motor/driver is a part of, and the easiest way to move forward with our testing was to disconnect the motor (to prevent it from moving unintentionally). After a few days of testing, we observed a board failure that seems to have stemmed from the DRV8844. I'm trying to figure out how the failure happened, and was wondering if there's any risk involved in commanding the DRV8844 to drive a motor that's disconnected? I can't find any info in the datasheet regarding protection against open load.
thanks,
Ryan
