Low impedance capacitors (C1~C4) should be connected as close as possible to the hybrid IC. 2. D1 requires approximately the same blocking voltage as the power modules. 3. If the reverse recovery time of D1 or D2 is long, Pin 22 or Pin 23 can end up with high voltage. For additional protection, insert a zener diode between Pin 18 and Pin 22 as well as between Pin 23 and Pin 27 as shown in the application example circuit. 4. If using an external Ctrip capacitor at Pin 21 or Pin 24, the Ctrip must be wired as close as possible to the IC’s pins (less than 5cm total). 5. The wiring length from the driver’s output to the IGBT’s gate should be kept as short as possible, as should the signal connections from the controller to the driver’s inputs in order to avoid errors caused by circuit noise. 6. A 4.7kΩ resistor can be connected between Pins 17 and 22 as well as between Pins 23 and 28 if short-circuit protection is not desired. In this case D1, D2, DZ1 and DZ4 should be left out and Pins 16 and 29 should be left unconnected. 7. Pins 1 and 42 are for manufacturing test purposes, and should be left unconnected. 4 VD = 15V ±5% VIN = 5V ±5% C1 ~ 4 = 100μF, 50V (Low Impedance) Ctrip1, Ctrip2 : Depended on RG1, RG2 (Aim : 0 ~ 47pF, 40V, Ceramic) CS1, CS2 : Depends on Serge Voltage Z1, Z4 : 30V DZ2, DZ3, DZ5, DZ6 : 18V D1, D2 : Fast Recovery Diode (trr : 0.2µs max.)

When an “ON” input signal is applied for a period longer than Ttrip and the collector voltage is high, the hybrid IC will recognize the condition as a short-circuit and immediately reduce the gate voltage. It will also produce a low voltage fault signal at the respective Pin 29 or Pin 16 alerting that the protection circuit is in operation. 2. The protection circuit will reset if an “OFF” input signal is applied and the minimum 1~2ms shutdown time has passed. “OFF” signal must be 10μs or more. 3. The controlled time to detect a short-circuit (Ttrip) should be set so that the IGBT can be fully turned “ON” before a short-circuit condition can be detected. It is possible to adjust Ttrip by connecting a capacitor (Ctrip) between Pins 17 and 21, as well as Pins 28 and 24. 4. When the short-circuit protection is activated, the soft gate shutdown circuit reduces the collector surge voltage on the IGBT. The gate shut down speed can be slowed even more by adding a capacitor to the CS terminal (between Pins 15 and 18; Pins 27 and 30). ts 13V 0V VO Operation Flow on Detecting Short Circuit START ts- CS CHARACTERISTICS (TYPICAL) DETECTION OF SHORT CIRCUIT GATE SHUTDOWN CIRCUIT OPERATE TIMER START OUTPUT FAULT SIGN END OF TIMER 1 ~ 2ms NO YES INPUT SIGN IS “OFF” FALL TIME ON ACTIVITY OF SHORT CIRCUIT PROTECTION, ts, (µs) 70 60 50 40 30 20 10 NO YES RESET 0 0 100 200 300 400 500 600 CONNECTIVE CAPACITANCE, CS, (pF) PIN: 15-18 (27 – 30) NOTE: “L” output voltage (VOL) with protection circuit operating is about VEE + 2V 05/16 Rev. 2 5 Powerex, Inc., 173 Pavilion Lane, Youngwood, Pennsylvania 15697 (724) 925-7272 www.pwrx.com VLA567-01R Hybrid IC IGBT Gate Driver + DC/DC Converter 20 18 18 16 16 14 14 12 10 8 6 2 0 -20 1.0 PROPAGATION DELAY TIME “L-H”, tPLH, (μs) PROPAGATION DELAY TIME “H-L”, tPHL, (μs) VCC, | VEE|, (VOLTS) 20 4 0.8 VD = 15V RG = 2Ω LOAD : C = 0.22μF f = 10kHz 0 20 40 60 12 10 8 6 DC LOAD VD = 15.8V VD = 15V VD = 14.2V 4 VCC | VEE | 2 0 80 0 20 40 60 80 AMBIENT TEMPERATURE, Ta, (°C) LOAD CURRENT, IO, (AMPERES) PIN: 18-20 (27-25) tPLH, tPHL-Ta CHARACTERISTICS (TYPICAL) tPLH, tPHL-VI CHARACTERISTICS (TYPICAL) 0.6 VD = 15V RG = 2Ω LOAD : C = 0.22μF tPLH tPHL 0.6 0.4 0.2 0 -20 0 20 40 60 AMBIENT TEMPERATURE, Ta, (°C) 6 VCC, | VEE | -IO CHARACTERISTICS (TYPICAL) PROPAGATION DELAY TIME “L-H”, tPLH, (μs) PROPAGATION DELAY TIME “H-L”, tPHL, (μs) VCC, | VEE|, (VOLTS) VCC, | VEE | CHARACTERISTICS (TYPICAL) 80 100 0.5 0.4 0.3 0.2 0.1 0 3.5 VD = 15V LOAD : C = 0.22μF tPLH tPHL 4.0 4.5 5.0 5.5 6.0 INPUT SIGNAL VOLTAGE, VI, (VOLTS) 05/16 Rev. 2 Powerex, Inc., 173 Pavilion Lane, Youngwood, Pennsylvania 15697 (724) 925-7272 www.pwrx.com VLA567-01R Hybrid IC IGBT Gate Driver + DC/DC Converter ttrip-Ta CHARACTERISTICS (TYPICAL) 5.0 8 VD = 15V RG = 2Ω LOAD : C = 0.22μF 4.0 3.5 3.0 2.5 2.0 1.5 1.0 ttrip1 (Ctrip = 0pF) ttrip2 (Ctrip = 47pF) 0.5 0 -20 0 20 40 60 4 3 2 0 100 150 200 250 300 CONNECTIVE CAPACITANCE, Ctrip, (pF) PIN: 17-21 (24-28) ID-IO CHARACTERISTICS (TYPICAL) VOH, | VOL | -Ta CHARACTERISTICS (TYPICAL) 20 0.4 0.3 0.2 0.1 0 50 AMBIENT TEMPERATURE, Ta, (°C) “H” OUTPUT VOLTAGE, VOH, (VOLTS) “L” OUTPUT VOLTAGE, | VOL |, (VOLTS) INPUT CURRENT, ID, (AMPERES) 5 0 80 VD = 15V DRIVING DOUBLE CIRCUIT 0.5 0.02 0.04 0.06 0.08 LOAD CURRENT, IO, (AMPERES) PIN: 44, 18-20 (27-25) 05/16 Rev. 2 6 1 0.6 0 VD = 15V RG = 2Ω LOAD : C = 0.22μF 7 CONTROLLED TIME DETECT SHORT CIRCUIT, ttrip, (μs) 4.5 CONTROLLED TIME DETECT SHORT CIRCUIT, ttrip1, ttrip2, (μs) ttrip-Ctrip CHARACTERISTICS (TYPICAL) 0.10 18 16 14 12 10 8 6 4 2 0 -20 VD = 15V RG = 2Ω LOAD : C = 0.22μF f = 10kHz 0 20 VOH | VOL | 40 60 80 AMBIENT TEMPERATURE, Ta, (°C) 7 Powerex, Inc., 173 Pavilion Lane, Youngwood, Pennsylvania 15697 (724) 925-7272 www.pwrx.com VLA567-01R Hybrid IC IGBT Gate Driver + DC/DC Converter 90 20 80 18 70 16 VCC, | VEE |, (VOLTS) EFFICIENCY, η, (%) η-Idrive CHARACTERISTICS (TYPICAL) 60 50 40 30 20 VD = 15V DRIVING DOUBLE CIRCUIT 0 0.02 0.04 0.06 0.08 10 8 6 0 14.0 0.10 IO = 0.1A VCC | VEE | 14.5 15.0 15.5 GATE DRIVE CURRENT, Idrive, (AMPERES) SUPPLY VOLTAGE, VD, (VOLTS) DERATING CHARACTERISTICS (TYPICAL) η-VD CHARACTERISTICS (TYPICAL) 90 16.0 0.10 85 0.08 EFFICIENCY, η, (%) GATE DRIVE CURRENT, Idrive, (AMPERES) 12 2 0.12 0.06 0.04 0.02 0 -20 LOAD : C = 0.22μF DRIVING DOUBLE CIRCUIT 0 20 80 75 VIN = 15.8V VIN = 15V VIN = 14.2V IO = 0.1A DRIVING DOUBLE CIRCUIT 40 60 AMBIENT TEMPERATURE, Ta, (°C) 8 14 4 10 0 VCC, | VEE | -VD CHARACTERISTICS (TYPICAL) 80 70 14.0 14.5 15.0 15.5 16.0 SUPPLY VOLTAGE, VD, (VOLTS) 05/16 Rev. 2
