To prevent the input signals oscillation, an RC coupling at each input is recommended. (see also Fig. 6)
(15V line)
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 5.1kΩ 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 terminals.
Fo output pulse width should be decided by connecting external capacitor between CFO and VNC terminals. (Example : CFO=22nF tFO=1.8ms (Typ.))
High voltage diodes (600V or more) 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.

Note1: In the recommended external protection circuit, please select the RC time constant in the range 1.5~2.0µs.
2: To prevent erroneous protection operation, the wiring of A, B, C should be as short as possible.
