Note 1 : To prevent the input signals oscillation, the wiring of each input should be as short as possible. (Less than 2cm)
Fig. 6 TYPICAL DIP-IPM APPLICATION CIRCUIT EXAMPLE
10 : To prevent ICs from surge destruction, it is recommended to insert a Zener diode (24V, 1W) between each control supply terminals.
11 : The reference voltage Vref of comparator should be set up the same rating of short circuit trip level (Vsc(ref): min.0.45V to max.0.52V).
12 : OR logic output level should be set up the same rating of short circuit trip level (Vsc(ref): min.0.45V to max.0.52V).
2 : By virtue of integrating an application specific type HVIC inside the module, direct coupling to MCU terminals without any opto-coupler
3 : F
4 : F
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
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-
