7 / 8 page MITSUBISHI SEMICONDUCTOR <Dual-In-Line Package Intelligent Power Module> PS21767-V TRANSFER-MOLD TYPE INSULATED TYPE Aug. 2007 7 MCU 10k Ω UP,VP,WP,UN,VN,WN VNC(Logic) Fo DIP-IPM 5V line [C] Under-Voltage Protection (Upper-arm, UVDB) c1. Control supply voltage rises : After the voltage level reaches UVDBr, the circuits start to operate. c2. Protection circuit state reset : IGBT ON and carrying current. c3. Normal operation : IGBT ON and carrying current. c4. Under-voltage trip (UVDBt). c5. IGBT OFF inspite of control input condition, but there is no FO signal output. c6. Under-voltage reset (UVDBr). c7. Normal operation : IGBT ON and carrying current. Fig. 5 RECOMMENDED MCU I/O INTERFACE CIRCUIT Note : RC coupling at each input (parts shown dotted) may change depending on the PWM control scheme used in the application and the wiring impedance of the application’s printed circuit board. The DIP-IPM input signal section integrates a 2.5k Ω(min) pull-down resistor. Therefore, when using a external filtering resistor, care must be taken to satisfy the turn-on threshold voltage requirement. Fig. 6 RECOMMENDED WIRING AROUND THE SHUNT RESISTOR Control input Protection circuit state Control supply voltage VDB Output current Ic Fault output Fo High-level (no fault output) UVDBr RESET SET RESET UVDBt c1 c3 c4 c5 c6 c7 c2 NW VNC NV NU DIP-IPM The GND wiring from VNO, VNC should be as close to the shunt resistors as possible VNO Each 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 |
