Single IGBT Gate Driver
The MC33153 is specifically designed as an IGBT driver for high power
applications that include ac induction motor control, brushless dc motor
control and uninterruptable power supplies. Although designed for driving
discrete and module IGBTs, this device offers a cost effective solution for
driving power MOSFETs and Bipolar Transistors. Device protection features
include the choice of desaturation or overcurrent sensing and undervoltage
detection. These devices are available in dual–in–line and surface mount
packages and include the following features:
• High Current Output Stage: 1.0 A Source/2.0 A Sink
• Protection Circuits for Both Conventional and Sense IGBTs
• Programmable Fault Blanking Time
• Protection against Overcurrent and Short Circuit
• Undervoltage Lockout Optimized for IGBT’s
• Negative Gate Drive Capability
• Cost Effectively Drives Power MOSFETs and Bipolar Transistors

APPLICATION INFORMATION
Figure 34 shows a basic IGBT driver application. When
driven from an optoisolator, an input pull up resistor is
required. This resistor value should be set to bias the output
transistor at the desired current. A decoupling capacitor
should be placed close to the IC to minimize switching noise.
A bootstrap diode may be used for a floating supply. If the
protection features are not required, then both the Fault
Blanking/Desaturation and Current Sense Inputs should both
be connected to the Kelvin Ground (Pin 2). When used with a
single supply, the Kelvin Ground and VEE pins should be
connected together. Separate gate resistors are
recommended to optimize the turn–on and turn–off drive.
If desaturation protection is desired, a high voltage diode
is connected to the Fault Blanking/Desaturation pin. The
blanking capacitor should be connected from the
Desaturation pin to the VEE pin. If a dual supply is used, the
blanking capacitor should be connected to the Kelvin
Ground. The Current Sense Input should be tied high
because the two comparator outputs are ANDed together.
Although the reverse voltage on collector of the IGBT is
clamped to the emitter by the free–wheeling diode, there is
normally considerable inductance within the package itself. A
small resistor in series with the diode can be used to protect
the IC from reverse voltage transients.

When used in a dual supply application as in Figure 35, the
Kelvin Ground should be connected to the emitter of the
IGBT. If the protection features are not used, then both the
Fault Blanking/Desaturation and the Current Sense Inputs
should be connected to Ground. The input optoisolator
should always be referenced to VEE.
When using sense IGBTs or a sense resistor, the sense
voltage is applied to the Current Sense Input. The sense trip
voltages are referenced to the Kelvin Ground pin. The sense
voltage is very small, typically about 65 mV, and sensitive to
noise. Therefore, the sense and ground return conductors
should be routed as a differential pair. An RC filter is useful in
filtering any high frequency noise. A blanking capacitor is
connected from the blanking pin to VEE. The stray
capacitance on the blanking pin provides a very small level of
blanking if left open. The blanking pin should not be grounded
when using current sensing, that would disable the sense.
The blanking pin should never be tied high, that would short
out the clamp transistor.
