*1 : Pre-drive power supply (VD4 = 15 ±1.5 V) must have the capacity of Io = 20 mA (DC), 0.5 A (Peak).
Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond the Recommended
Operating Ranges limits may affect device reliability.
Usage Precaution
1. This IPM includes internal bootstrap diode and resistor. By adding a bootstrap 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. The “FLTEN” terminal (Pin 18) is I/O terminal; Fault output / Enable input. It is used to indicate an internal fault condition of the module
and also can be used to disable the module operation.
4. 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.
5. The pull-down resistor (: 33 kΩ (typ)) is connected with the inside of the signal input terminal, but please connect the pull-down resistor
(about 2.2 to 3.3 kΩ) outside to decrease the influence of the noise by wiring etc.
6. As protection of IPM to the unusual current by a short circuit etc., it recommends installing shunt resistors and an over-current protection
circuit outside. Moreover, for safety, a fuse on VCC line is recommended.
7. Disconnection of terminals U, V, or W during normal motor operation will cause damage to IPM, use caution with this connection.
.
8. The “ITRIP” terminal (Pin 16) is the input terminal to shut down. When VITRIP exceeds threshold (0.44 V to 0.54 V) all IGBT’s are
turned off. And normal operation resumes 2 ms (typ) after over current condition is removed. Therefore, please turn all the input
signals off (Low) in case of detecting error at the “FLTEN” terminal.
9. When input pulse width is less than 1 μs, an output may not react to the pulse. (Both ON signal and OFF signal)
This data shows the example of the application circuit and does not guarantee a design as the mass production set.
