9 / 10 page MITSUBISHI SEMICONDUCTOR <Dual-In-Line Package Intelligent Power Module> PS21964-4/-4A/-4C/-4W TRANSFER-MOLD TYPE INSULATED TYPE Aug. 2007 9 MCU 10k Ω UP,VP,WP,UN,VN,WN VNC(Logic) Fo DIP-IPM 5V line 3.3k Ω (min) Error output Fo Output current Ic Control supply voltage VDB Protection circuit state Control input c6 c1 c2 c4 c5 c3 RESET UVDBt UVDBr SET RESET High-level (no fault output) [C] Under-Voltage Protection (Upper-side, UVDB) c1. Control supply voltage rising : After the voltage level reaches UVDBr, the circuits start to operate when next input is applied. c2. Normal operation : IGBT ON and carrying current. c3. Under voltage trip (UVDBt). c4. IGBT OFF in spite of control input signal level, but there is no FO signal outputs. c5. Under voltage reset (UVDBr). c6. Normal operation : IGBT ON and carrying current. Fig. 9 RECOMMENDED MCU I/O INTERFACE CIRCUIT Note : The setting of RC coupling at each input (parts shown dotted) depends on the PWM control scheme and the wiring impedance of the printed circuit board. The DIP-IPM input section integrates a 3.3k Ω (min) pull-down resistor. Therefore, when using an external filtering resistor, pay attention to the turn-on threshold voltage. Fig. 10 WIRING CONNECTION OF SHUNT RESISTOR N DIP-IPM Wiring inductance should be less than 10nH. Shunt resistor Equivalent to the inductance of a copper pattern in dimension of width=3mm, thickness=100 µm, length=17mm Please make the GND wiring connection of shunt resistor to the VNC terminal as close as possible.
