Note1: 2: 3: 4:
5: 6:
To prevent the input signals oscillation, an RC coupling at each input is recommended. (see also Fig. 6) By virtue of integrating an application specific type HVIC inside the module, direct coupling to CPU terminals without any opto-coupler or transformer isolation is possible. (see also Fig. 6) This output is open collector type. The signal line should be pulled up to the positive side of the 5V power supply with approximately 5.1k resistance. (see also Fig. 6) The wiring between the power DC link capacitor and the P/N1 terminals should be as short as possible to protect the DIP-IPM against catastrophic high surge voltages. For extra precaution, a small film type snubber capacitor (0.1~0.22µF, high voltage type) is recommended to be mounted close to these P and N1 DC power input pins. Fo output pulse width should be decided by putting external capacitor between CFO and VNC terminals. (Example : CFO=22nF tFO=1.8ms (Typ.)) High voltage (600V or more) and fast recovery type (less than 100ns) diodes should be used in the bootstrap circuit.

Short Circuit Protective Function (SC) : SC protection is achieved by sensing the L-side DC-Bus current (through the external shunt resistor) after allowing a suitable filtering time (defined by the RC circuit). When the sensed shunt voltage exceeds the SC trip-level, all the L-side IGBTs are turned OFF and a fault signal (Fo) is output. Since the SC fault may be repetitive, it is recommended to stop the system when the Fo signal is received and check the fault.

The long wiring of GND might generate noise on input signals and cause IGBT to be malfunctioned.
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, an RC coupling at each input is recommended, and 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 CPU terminals without any opto-coupler or transformer isolation is possible. 3 : FO output is open collector type. This signal line should be pulled up to the positive side of the 5V power supply with approximately 5.1k resistance. 4 : FO output pulse width should be decided by connecting an external capacitor between CFO and VNC terminals (C FO). (Example : CFO = 22 nF tFO = 1.8 ms (typ.)) 5 : Each input signal line should be pulled up to the 5V power supply with approximately 4.7k resistance (other RC coupling circuits at each input may be needed depending on the PWM control scheme used and on the wiring impedances of the system's printed circuit board). Approximately a 0.22~2µF by-pass capacitor should be used across each power supply connection terminals. 6 : To prevent errors of the protection function, the wiring of A, B, C should be as short as possible. 7 : In the recommended protection circuit, please select the R1C5 time constant in the range 1.5~2µs. 8 : Each capacitor should be put 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. Approximately a 0.1~0.22µF snubber capacitor between the P&N1 pins is recommended.
