the IGBT is in the off−state, it will be subjected to changes

a problem when the opposite transistor turns on.
diode, the turn−on dv/dt of the lower device appears across
the collector emitter of the upper device. To eliminate
shoot−through currents, it is necessary to provide a low sink
impedance to the device that is in the off−state. In most
applications the turn−off resistor can be made small enough
to hold off the device that is under commutation without
causing excessively fast turn−off speeds.
the off−state. This is a practice carried over from bipolar
Darlington drives and is generally not required for IGBTs.
However, a negative bias will reduce the possibility of
shoot−through. The MC33153 has separate pins for V
Kelvin Ground. This permits operation using a +15/−5.0 V
supply.

and if desired, isolation from ac line voltages. An
optoisolator with a very high dv/dt capability should be
used, such as the Hewlett Packard HCPL4053. The IGBT
gate turn−on resistor should be set large enough to ensure

that the opto’s dv/dt capability is not exceeded. Like most
optoisolators, the HCPL4053 has an active low
open−collector output. Thus, when the LED is on, the output
will be low. The MC33153 has an inverting input pin to
interface directly with an optoisolator using a pullup
resistor. The input may also be interfaced directly to 5.0 V
CMOS logic or a microcontroller.

is important that all faults are properly reported, it is equally
important that no false signals are propagated. Again, a high
dv/dt optoisolator should be used.

when off. An active high output, resistor, and small signal
diode provide an excellent LED driver. This circuit is shown
in Figure 33.

voltage. IGBTs require 15 V on the gate to achieve the rated
on−voltage. At gate voltages below 13 V, the on−voltage
increases dramatically, especially at higher currents. At very
low gate voltages, below 10 V, the IGBT may operate in the
linear region and quickly overheat. Many PWM motor
drives use a bootstrap supply for the upper gate drive. The
UVLO provides protection for the IGBT in case the
bootstrap capacitor discharges.
UVLO circuit has about 1.0 V of hysteresis and will disable
the output if the supply voltage falls below about 11 V.
PROTECTION CIRCUITRY
Desaturation Protection

monitoring the collector voltage and turning off the device
if this voltage rises above a certain limit. A bipolar transistor
will only conduct a certain amount of current for a given
base drive. When the base is overdriven, the device is in
