QC962-L Datasheet, PDF (2/2 Pages) MORNSUN Science& Technology Ltd. – Hybrid Integrated IGBT Driver

APPLICATION EXAMPLES
QC962-L
TTL compatible input interface
Duty:50%
VIN=5V
RG=3.1Ω
D1 :Fast Recovery Diode(trr≤0.2μs)
f=20kHz
VCC=15V
VEE=10V
Ctrip=0~3300pF
APPLICATION NOTES
1. The IGBT gate-emitter drive loop wiring must be shorter
than one meter.
2. The IGBT gate-emitter drive loop wiring should be
twisted.
3. If large voltage spike is generated at the collector of the
IGBT, increase the IGBT gate resistor.
4. Pin3,7,9,10 are used only for the test circuit and not be
connected with the application circuit.
5. The external blocking capacitors must be connected as
close as possible to the driver’s pin.
6. Peak reverse voltage of the diode D1 must be higher than
the peak value of the IGBT collector voltage.
7. The distance between the capacitor Ctrip and pin2-4
should be as short as possible(Max.5cm)
8. Pin1 voltage could be high due to the reverse recovery
characteristic of the diode D1 and the 30V zener diode
DZ1 is connected between pin1 and pin6 for protecting
the driver.
9. The input signal voltage must be less than 5.25V. The
higher input signal voltage, the higher input signal
current. It will result in more dissipation. The input port is
a circuit composed of a high-speed optocoupler series
with a 150ohm resistor. Practically, a current-limiting
resistor is inserted, which value can be obtained
according to the following equation:
R = ^{Vin −1.7V} −150ohm
16mA
