Hi team
My customer needs some diagnose function like short to GND/open load/short to battery detection. Currently at OFF state customer used external output pull-up resistor to distinguish the open load fault.
The customer requires that in the ON state, it is also necessary to distinguish between the open load fault and the short to the battery fault, but I think the chip seems to be indistinguishable. The two faults are judged by the current of the SNS pin less than a certain value, but they cannot be distinguished specifically whether it is open load or short to battery fault.
Therefore, in the ON state mode of the chip, what is the recommended design to distinguish between these two types of faults (short to battery or open load)? Thank you.
