The short circuit event is highly critical for any system especially the BMS. The integrated short circuit protection comparator can be diagnosed to check its functionality by using the SCP_TEST pin. When the SCP_TEST pin is driven low to high then, a voltage is applied internally across the SCP comparator inputs to simulate a short circuit event. If the gate drive and FLT goes low then it indicates that the internal short circuit protection comparator is good otherwise it is to be treated as SCP feature is not functional. If the SCP_TEST feature is not used, then connect SCP_TEST pin to GND. The SCP comparator diagnosis can be performed before system startup.
