9 / 16 page 9 www.fairchildsemi.com FSBB20CH60 Rev. C Time Charts of SPMs Protective Function a1 : Control supply voltage rises: After the voltage rises UVCCR, the circuits start to operate when next input is applied. a2 : Normal operation: IGBT ON and carrying current. a3 : Under voltage detection (UVCCD). a4 : IGBT OFF in spite of control input condition. a5 : Fault output operation starts. a6 : Under voltage reset (UVCCR). a7 : Normal operation: IGBT ON and carrying current. Figure 6. Under-Voltage Protection (Low-side) b1 : Control supply voltage rises: After the voltage reaches UVBSR, the circuits start to operate when next input is applied. b2 : Normal operation: IGBT ON and carrying current. b3 : Under voltage detection (UVBSD). b4 : IGBT OFF in spite of control input condition, but there is no fault output signal. b5 : Under voltage reset (UVBSR) b6 : Normal operation: IGBT ON and carrying current Figure 7. Under-Voltage Protection (High-side) Input Signal Output Current Fault Output Signal Control Supply Voltage RESET UV CCR Protection Circuit State SET RESET UV CCD a1 a3 a2 a4 a6 a5 a7 Input Signal Output Current Fault Output Signal Control Supply Voltage RESET UV BSR Protection Circuit State SET RESET UV BSD b1 b3 b2 b4 b6 b5 High-level (no fault output) |
