Hello Michael,
Thanks for your answer and have some more question as below.
If first threshold set by the Rshunt resistor is not actually a fault condition, why DRV3220 switching off the internal low side boost FET?
Seems that customer can't clarity the exact root cause when internal low side boost FET is shut down by itself.
Customer want to know how to check coil current is exceed the limited setting value with Rboost_shunt and why DRV3220 shut down internal low side boost FET even though that is not a fault condition.
And, Can you provide formula how to calculate total power dissipation on DRV3220?
Thanks
Anthony Kim
