10) Error signal output width (t FO ) can be set by the capacitor connected to the C FO terminal. t FO(typ) = C FO / 9.1 x 10 -6 (s).
11) Input drive is high-active type. There is a 3.3k pull-down resistor integrated in the IC input circuit. To prevent malfunction, the wiring of each input
If control GND is connected to power GND by broad pattern, it may cause malfunction by power GND fluctuation.
It is recommended to connect control GND at only a point at which NU, NV, NW are connected to power GND line.
To prevent surge destruction, the wiring between the smoothing capacitor and the P-N1 terminals should be as short as
possible. Generally inserting a 0.1µ ~ 0.22µF snubber capacitor C 3 between the P-N1 terminals is recommended.
The time constant R 1 ,C 4 of RC filter for preventing the protection circuit malfunction should be selected in the range of 1.5µ ~ 2µs.
SC interrupting time might vary with the wiring pattern. Tight tolerance, temp-compensated type is recommended for R 1 ,C 4 .
All capacitors should be mounted as close to the terminals of the DIPIPM as possible. (C 1 : good temperature, frequency
characteristics electrolytic type, and C 2 : good temperature, frequency and DC bias characteristic ceramic type are recommended.)
It is recommended to insert a Zener diode DZ 1 (24V/1W) between each pair of control supply terminals to prevent surge destruction.
To prevent erroneous SC protection, the wiring from V SC terminals to C IN filter should be divided at the point D that is close
to the terminal of sense resistor and the wiring should be patterned as short as possible.
For sense resistor, the variation within 1% (including temperature characteristics), low inductance type is recommended.
1/8W is recommended, but an evaluation of your system is recommended.
To prevent erroneous operation, wiring A, B, and C should be as short as possible.
F O output is open drain type. It should be pulled up to the positive side of 5V or 15V power supply with a resistor that limits
F O sink current (I FO ) under 1mA. (Over 5.1k is needed and 10k is recommended for 5V supply.)
should be patterned as short as possible. When inserting the RC filter, make sure the input signal level meets the turn-on and turn-off threshold voltage.
Thanks to HVIC inside the module, connection to the MCU may be direct or with an opto-coupler.
