• Manufacturer: Mitsumi Electronics, Corp.

Note 1 : Input drive is High-Active type. There is a 3.3kΩ(min.) pull-down resistor integrated in the IC input circuit. To prevent malfunction, the wiring of each in-

2 : Thanks to HVIC inside the module, direct coupling to MCU without any opto-coupler or transformer isolation is possible.
3 : F
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
6 : All capacitors should be mounted as close to the terminals of the DIP-IPM as possible. (C1: good temperature, frequency character-
7 : To prevent surge destruction, the wiring between the smoothing capacitor and the P, N1 terminals should be as short as possible.
8 : Two V
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 to power GND by broad pattern, it may cause malfunction by power GND fluctuation. It is recommended
11 : The reference voltage Vref of comparator should be set up the same rating of short circuit trip level (Vsc(ref): min.0.43V to max.0.53V).
12 : OR logic output high level should exceed the maximum short circuit trip level (Vsc(ref): max.0.53V).

Generally a 0.1-0.22µF snubber between the P-N1 terminals is recommended.
