• Manufacturer Part Number: PS21267-P-AP
• Manufacturer: MITSUBISHI

Note 1 : To prevent the input signals oscillation, the wiring of each input should be as short as possible. (Less than 2-3cm)
Fig. 10 EXAMPLE OF TYPICAL DIP-IPM APPLICATION CIRCUIT
10 : To prevent IC
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 2.5kΩ (min) pull-down resistor. If using external
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-

output is open drain type. This signal line should be pulled up to the positive side of the 5V power supply with approximately 10kΩ
output pulse width is determined by the external capacitor between CFO and V
