• Manufacturer: Mitsumi Electronics, Corp.

Note 1 : To prevent the input signals oscillation, the wiring of each input should be as short as possible. (Less than 2cm)
Fig. 10 TYPICAL DIP-IPM APPLICATION CIRCUIT EXAMPLE
10 : It is recommended to insert a Zener diode (24V/1W) nearby each pair of supply terminals to prevent surge destruction.
2 : By virtue of integrating an application specific type HVIC inside the module, direct coupling to MCU terminals without any opto-coupler
3 : F
4 : F
5 : The logic of input signal is high-active. The DIP-IPM input signal section integrates a 2.5k (min) pull-down resistor. Therefore, when
6 : To prevent malfunction of protection, the wiring of A, B, C should be as short as possible.
7 : Please set the R
8 : Each capacitor should be located as nearby the pins of the DIP-IPM as possible.
9 : To prevent surge destruction, the wiring between the smoothing capacitor and the P, N1 pins should be as short as possible. Approxi-
