Fig. 6 TYPICAL DIP-IPM APPLICATION CIRCUIT EXAMPLE
Note 1 : To prevent malfunction, the wiring of each input should be as short as possible (2~3cm).
2 : By virtue of integrating HVIC inside, direct coupling to MCU without opto-coupler or transformer isolation is possible.
3 : F
4 : The logic of input signal is high-active. The DIP-IPM input signal section integrates a 3.3k
5 : To prevent malfunction of protection, the wiring of A, B, C should be as short as possible.
6 : Please set the filter R1• C4 time constant such that the IGBT can be interrupted within 2 s.
7 : Each capacitor should be located as nearby the pins of the DIP-IPM as possible.
8 : To prevent surge destruction, the wiring between the smoothing capacitor and the P-N1 pins should be as short as possible.
9 : Make external wiring connection between V
10 : Two V
11 : To prevent ICs from surge destruction, it is recommended to insert a Zener diode (24V, 1W) between each control supply terminals.
12 : The reference voltage Vref of comparator should be set up the same rating of short circuit trip level (Vsc(ref): min.0.43V to
13 : OR logic output level should be set up the same rating of short circuit trip level (Vsc(ref): min.0.43V to max.0.53V).
C1:Tight tolerance temp-compensated electrolytic type
If using external filtering resistor, ensure the voltage drop of ON signal not below the threshold value.
Approximately a 0.1~0.22 F snubber capacitor between the P-N1 pins is recommended.
