Dear all,

I would like to know the function of FAULT and UVLO.

1. Please teach me the motion of motor when the FAULT is active.

I think that the motor rotates to the original position under FAULT function.

But I don't know the speed.

Does the motor rotate to the original position quickly? or slowly?

2. Please teach me the reason why UVLO is set to 7.8V.

My customer want this device not to be inactive around 6V to deal with cold cranking.

Please teach me the way to be inactive UVLO if there is the way.

Or, I would like to know the reason why UVLO is set to 7.8V.

Best regards,
