F R-category ceramic capacitor for noise filtering.
Note1:
To prevent the input signals oscillation, an RC coupling at each input is recommended. (see also Fig. 6)
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. (see also Fig. 6)
3:
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)
4:
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 (0.1~0.22
μ
F, high voltage type) is recommended to be mounted close to
these P and N1 DC power input terminals.
5:
Fo output pulse width should be decided by connecting external capacitor between CFO and V

6:
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.
