Note1: In the recommended external protection circuit, please select the RC time constant in the range 1.5~2.0

µs.

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

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.

µF R-category ceramic capacitor for noise filtering.

(Note : The capacitance value depends on the PWM control

scheme used in the applied system).

Note1:

Input logic is high-active. There is a 2.5k

Ω (min) pull-down resistor built-in each input circuit. When using an external CR filter, please make it satisfy the

input threshold voltage.

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. (see also Fig. 8)

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

Ω resistance.

(see also Fig. 8)

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

µF, high voltage type) is recommended to be mounted close to

these P-N1 DC power input pins.

5:

6:

High voltage (600V or more) and fast recovery type (less than 100ns) diodes should be used in the bootstrap circuit.

7:

8:

To prevent ICs from surge destruction, it is recommended to insert a Zener diode (24V, 1W) nearby each pair of supply terminals.
