Usage Precautions
1. This IPM includes bootstrap diode and resistors. Therefore, by adding a capacitor “CB”, a high side drive voltage is generated;
each phase requires an individual bootstrap capacitor. The recommended value of CB is in the range of 1 to 47 μF, however this
value needs to be verified prior to production. If selecting the capacitance more than 47 μF (±20%), connect a resistor (about 20 Ω)
in series between each 3-phase upper side power supply terminals (VB1, 2, 3) and each bootstrap capacitor.
When not using the bootstrap circuit, each upper side pre-drive power supply requires an external independent power supply.
2. It is essential that wirning length between terminals in the snubber circuit be kept as short as possible to reduce the effect of
surge voltages. Recommended value of “CS” is in the range of 0.1 to 10 μF.
3. “ISO” (pin 24) is terminal for current monitor. When the pull-down resistor is used, please select it more than 5.6 kΩ
4. “FAULT” (pin 23) is open DRAIN output terminal. (Active Low). Pull up resistor is recommended more than 5.6 kΩ.
5. Inside the IPM, a thermistor used as the temperature monitor for internal subatrate is connected between VSS terminal and TH
terminal, therefore, an external pull up resistor connected between the TH terminal and an external power supply should be
used. The temperature monitor example application is as follows, please refer the Fig.10, and Fig.11 below.
6. Pull down resistor of 33 kΩ is provided internally at the signal input terminals. An external resistor of 2.2 k to 3.3 kΩ should be
added to reduce the influence of external wiring noise.
7. The over-current protection feature is not intended to protect in exceptional fault condition. An external fuse is recommended for
safety.
8. When “-” and “VSS” terminal are short-circuited on the outside, level that over-current protection (ISD) might be changed from
designed value as IPM. Please check it in your set (“N” terminal and “VSS” terminal are connected in IPM).
9. The over-current protection function operates normally when an external resistor RSD is connected between ISD and VSS
terminals. Be sure to connect this resistor. The level of the overcurrent protection can be changed according to the RSD value.
10. When input pulse width is less than 1.0 μs, an output may not react to the pulse. (Both ON signal and OFF signal)
