Fig. 8 TYPICAL DIP-IPM APPLICATION CIRCUIT EXAMPLE
Note 1 : To prevent the input signals oscillation, an RC coupling at each input is recommended, and the wiring of each input should be as short
as possible. (Less than 2cm)
2: By virtue of integrating an application specific type HVIC inside the module, direct coupling to CPU terminals without any opto-coupler
or transformer isolation is possible.
3: FO output is open collector type. This signal line should be pulled up to the positive side of the 5V power supply with approximately
5.1k
resistance.
4: FO output pulse width should be decided by connecting an external capacitor between CFO and VNC terminals (CFO). (Example : CFO
= 22 nF
→ tFO = 1.8 ms (typ.))
5: Each input signal line should be pulled up to the 5V power supply with approximately 4.7k
resistance (other RC coupling circuits at
each input may be needed depending on the PWM control scheme used and on the wiring impedances of the system’s printed circuit
board). Approximately a 0.22~2
F by-pass capacitor should be used across each power supply connection terminals.
6: To prevent errors of the protection function, the wiring of A, B, C should be as short as possible.
7: In the recommended protection circuit, please select the R1C5 time constant in the range 1.5~2
s.
8: Each capacitor should be put 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 0.1~0.22
F snubber capacitor between the P&N1 pins is recommended.

C1: Tight to lerance temp-compensated electrolytic type; C2,C3: 0.22~2
F R-category ceramic capacitor for noise filtering
(Note : The capacitance value depends on the PWM control used in the applied system)
