Typical Connection
Connection Notes:
To minimize the potential for problems (and/or
failures) caused by induced noise, EMI interference and/or oscillation, the connection of the
gate driver must be done with great care. Some
recommendations would include:
1.
The input signal voltage (pin 14) cannot exceed 5.25V. The internal dissipation caused
by the resultant increase in input current could
damage the input optocoupler. A current limiting resistor (R1) is used to help prevent this.
The resistor value is calculated by the formula:
R1 = VIN - 1.7V - 150X
16 mA
2.
3.
4.
5.
6.
7.
8.
9.
The gate wiring of the IGBT gate-emitter drive
loop must be shorter than 1 meter.
Twisted pair wiring is recommended for the
gate-emitter drive loop to minimize mutual
induction.
Pins 4, 7, 8, 10 and 11 (not shown in the
connection diagram) of the IGD841 are only
used for testing. They should not be used as
a connection in any application circuit.
If a large voltage spike is generated at the
IGBT collector, the value of the gate resistor
(RG) should be increased.
Smoothing capacitors C2 and C3 should be
mounted as close to the driver as possible.
An internal circuit sets up a -5V off-gate voltage
at pin 9 to protect against faults in the off state.
Do not apply an external voltage to pin 1.
The peak reverse voltage rating of D1 must
be higher than the peak value of the IGBT
collector voltage.
The traces (or wires) between the power
source (VCC) and the driver circuit should be
as short as possible.
