When the sensed shunt voltage exceeds the SC trip-level, all the N-side IGBTs are turned OFF and a fault signal (Fo) is output. Since the SC fault may be repetitive, it is recommended to stop the system when the Fo signal is received and check the fault.

To prevent malfunction, the wiring of each input should be as short as possible. When using RC coupling circuit, make sure the input signal level meet the turn-on and turnoff threshold voltage. 2 : Thanks to HVIC inside the module, direct coupling to MCU without any opto-coupler or transformer isolation is possible. 3 : Fo output is open drain type. It should be pulled up to the MCU or control power supply (e.g. 5V, 15V) by a resistor that makes IFo up to 1mA. 4 : To prevent erroneous protection, the wiring of A, B, C should be as short as possible. 5 : The time constant R1C4 of the protection circuit should be selected in the range of 1.5-2µs. SC interrupting time might vary with the wiring pattern. Tight tolerance, temp-compensated type is recommended for R1, C4 6 : All capacitors should be mounted as close to the terminals of DIPIPM as possible. (C1: good temperature, frequency characteristic electrolytic type, and C2, C3 (0.22~2µF) : good temperature, frequency and DC bias characteristic ceramic type are recommended.) 7 : To prevent surge destruction, the wiring between the smoothing capacitor and the P, N1 terminals should be as short as possible. Generally a 0.1-0.22µF snubber between the P-N1 terminals is recommended. 8 : Two VNC terminals (9 & 16 pin) are connected inside DIPIPM, please connect either one to the 15V power supply GND and leave the other open. 9 : It is recommended to insert a Zener diode (24V/1W) between each pair of control supply terminals to prevent surge destruction. 10 : If control GND is connected with power GND by common broad pattern, it may cause malfunction by power GND fluctuation. It is recommended to connect control GND and power GND at only a point N1. 11 : High voltage (VRRM =600V or more) and fast recovery type (trr=100ns or less) diodes should be used in the bootstrap circuit.
