RE: DRV8812: Risense of DRV8812

Hi Hasebe-san, I am glad to hear both mixed and fast decay agree. Slow decay may not be able to control the current at slow motor speeds. If the current reduction during the slow decay time is less...

RE: DRV8307: Using CSD18540Q5BT MOSFETs with DRV8307

Hi Stephen,Thank you for the detailed information.  The 1.8V spike measured on the ISENSE line is not expected, this sounds like a shoot through type of event.  This should be triggering the OCP...
