The long wiring of GND might generate
noise on input and cause IGBT to
be malfunction.
If this wiring is too long, the SC level
fluctuation might be larger and cause
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.
