Fig. 8 TYPICAL DIP-IPM APPLICATION CIRCUIT EXAMPLE
Note 1 : To prevent the input signals oscillation, 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 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 10k
resistor.
4: FO output pulse width is determined by the external capacitor between CFO and VNC terminals (CFO). (Example : CFO = 22 nF
→ tFO
= 1.8 ms (typ.))
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
using external filtering resistor, care must be taken to satisfy the turn-on 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 C5R1 time constant in the range 1.5~2
s.
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 0.1~0.22
F snubber capacitor between the P-N1 pins is recommended.
10 : The terminal VNO should be connected with the terminal N outside.
11 : To prevent ICs from surge destruction, it is recommended to insert a Zener diode (24V, 1W) nearby each pair of supply terminals.

Long GND wiring here might generate
noise to input and cause IGBT

If this wiring is too long, the SC level
fluctuation might be larger and cause
SC malfunction.
Too long wiring here might
cause short-circuit.
