(Note : Additionally, an appropriate line-to line
surge absorber circuit may become necessary
depending on the application environment.)
In the recommended external protection circuit, please select the RC
time constant in the range 1.5~2.0µs.
To prevent erroneous protection operation, the wiring of A, B, C should
be as short as possible.

(Note : The capacitance value depends on the PWM control
The logic of input signal is high-active. The DIP-IPM input signal section integrates a 2.5kΩ(min) pull-down resistor.
By virtue of integrating an application specific type HVIC inside the module, direct coupling to MCU terminals without any opto-coupler or transformer
This output is open drain type. The signal line should be pulled up to the positive side of the 5V power supply with approximately 10kΩ resistor.
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
Fo output pulse width should be decided by putting external capacitor between CFO and V
High voltage (600V or more) and fast recovery type (less than 100ns) diodes should be used in the bootstrap circuit.
To prevent IC
If using external RC filter, pay attention to satisfy the turn-on/off threshold voltage requirement.

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.
