SC malfunction.
Note 1 : To prevent the input signals oscillation, the wiring of each input should be as short as possible. (Less than 2-3cm)
2 : By virtue of integrating an application specific type HVIC inside the module, direct coupling to MCU terminals without any opto-coupler
or transformer isolation is possible.
3 : FO output is open drain type. This signal line should be pulled up to the positive side of the 5V power supply with approximately 10kΩ
resistor.
4 : FO output pulse width is determined by the external capacitor between CFO and VNC terminals (CFO). (Example : CFO = 22nF → tFO
= 1.8ms (typ.))
5 : The logic of input signal is high-active. The DIP-IPM input signal section integrates a 2.5kΩ (min) pull-down resistor. If using external
RC filter, pay attention to satisfy the turn-on/off threshold voltage requirement.
6 : To prevent malfunction of protection, the wiring of A, B, C should be as short as possible.
7 : Please set the R1C5 time constant in the range 1.5~2µs.
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-
mately a 0.1~0.22µF snubber capacitor between the P-N1 pins is recommended.
10 : To prevent ICS from surge destruction, it is recommended to insert a Zener diode (24V, 1W) between each control supply terminals.
