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 1.5~2.0
s.
2:
To prevent erroneous protection operation, the wiring of A, B, C should
be as short as possible.

DIP-IPM

(Note : Additionally, an appropriate line-to line
surge absorber circuit may become necessary
depending on the application environment.)

C1 : Tight tolerance, temp-compensated electrolytic type

F R-category ceramic capacitor for noise filtering
(Note : The capacitance value depends on the PWM control
scheme used in the applied system.)
Note1:
The logic of input signal is high-active. The DIP-IPM input signal section integrates a 2.5k
(min) pull-down resistor.
If using external RC filter, pay attention to satisfy the turn-on/off threshold voltage requirement.
2:
By virtue of integrating an application specific type HVIC inside the module, direct coupling to MCU terminals without any opto-coupler or transformer
isolation is possible.
3:
This output is open drain type. The signal line should be pulled up to the positive side of the 5V power supply with approximately 10k
resistor.
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
F, high voltage type) is recommended to be mounted close to
these P & N1 DC power input pins.
5:
Fo output pulse width should be decided by putting external capacitor between CFO and VNC terminals. (Example : CFO=22nF
→ tFO=1.8ms (Typ.))
6:
High voltage (600V or more) and fast recovery type (less than 100ns) diodes should be used in the bootstrap circuit.
7:
To prevent ICS from surge destruction, it is recommended to insert a Zener diode (24V, 1W) between each control supply terminals.
