In the safety critical designs, short-circuit protection (SCP) feature and its diagnosis is important.

The TPS12000-Q1 features the diagnosis of the internal short circuit protection. When SCP_TEST is driven low to high then, a voltage is applied internally across the SCP comparator inputs to simulate a short circuit event. The comparator output controls the gate drive (PU/PD) and also the FLT. If the gate drive goes low (with initially being high) and FLT alos goes low then it indicates that the SCP 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.
