The logic of input signal is high-active. The DIP-IPM input signal section integrates a 2.5kΩ(min) pull-down resistor.
If using external RC filter, pay attention to satisfy the turn-on/off threshold voltage requirement.
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.
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
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 & 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.
To prevent ICS from surge destruction, it is recommended to insert a Zener diode (24V, 1W) between each control supply terminals.
Fig. 3 EXTERNAL PART OF THE DIP-IPM PROTECTION CIRCUIT
DIP-IPM
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.

Note 1 : To prevent the input signals oscillation, the wiring of each input should be as short as possible. (Less than 2-3cm)
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 : FO output is open drain type. This signal line should be pulled up to the positive side of the 5V power supply with approximately 10kΩ
resistor.
4 : FO output pulse width is determined by the external capacitor between CFO and VNC terminals (CFO). (Example : CFO = 22nF → tFO
= 1.8ms (typ.))
5 : The logic of input signal is high-active. The DIP-IPM input signal section integrates a 2.5kΩ (min) pull-down resistor. If using external
RC filter, pay attention to satisfy the turn-on/off threshold voltage requirement.
6 : To prevent malfunction of protection, the wiring of A, B, C should be as short as possible.
7 : Please set the R1C5 time constant in the range 1.5~2µs.
8 : Each capacitor should be located 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.
10 : To prevent ICS from surge destruction, it is recommended to insert a Zener diode (24V, 1W) between each control supply terminals.
