3.4.6 Short-Circuit Detection System

The short-circuit detection system on the board provides protection in case of a short-circuit event. When a short circuit is detected, the gate driver pulls the OUTL low with a fixed current soft turn-off, and the FLT flag will be raised on the primary side. If the short-circuit detection system is not used or if an IGBT/MOSFET is not connected to the board, J4and J5 should be shorted to respective HS and LS COM to prevent false short-circuit triggering.
