Usage Precautions 1. This H-IC includes internal bootstrap diodes and resistors. 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 47μF (±20%), however this value needs to be verified prior to production. If selecting the capacitance more than 47μF (±20%), connect a resistor (about 40Ω) 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 n 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 10μF. 3. ”FAULT” (16pin) is open DRAIN output terminal (Active Low). Pull up resistor is recommended more than 5.6kΩ. 4. Inside the H-IC, a thermistor used as the temperature monitor for internal substrate is connected between “TH1” and “TH2” . Generally, one of terminals is connected to VSS, and the other is pulled up to external power supply with pull-up resistor (Rp) externally. The temperature monitor example application is as follows please refer the Fig.11 and Fig.12 below. 5. The pull-down resistor 33kΩ is provided internally at the signal input terminals. An external resistor of 2.2kΩ to 3.3kΩ should be added to reduce the influence of external wiring noise. 6. As protection of H-IC to unusual current by a short circuit etc, it recommended 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, W, during normal motor operation will cause damage to H-IC, use caution with this connections. 8. The “ITRIP” terminal (17pin) is the input terminal to shut down. When VITRIP exceeds threshold (0.44V to 0.54V), all IGBTs are turned off. And normal operation resumes 2ms(typ) after over current condition is removed. Therefore, please turn all the input signal off (Low) in case of detecting error at the “FAULT” terminal. 9. When input pulse width is less than 1us, an output may not react to the pulse. (Both ON signal and OFF signal) |
