MOTOROLA ANALOG IC DEVICE DATA
When the lower device is turned on, clearing the upper
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.

A negative bias voltage can be used to drive the IGBT into
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 VEE and
Kelvin Ground. This permits operation using a +15/–5.0 V
supply.
INTERFACING WITH OPTOISOLATORS
Isolated Input
The MC33153 may be used with an optically isolated
input. The optoisolator can be used to provide level shifting,
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 pull up resistor. The input may also be interfaced
directly to 5.0 V CMOS logic or a microcontroller.
Optoisolator Output Fault
The MC33153 has an active high fault output. The fault
output may be easily interfaced to an optoisolator. While it 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.
The LED drive provides a resistor programmable current
of 10 to 20 mA when on, and provides a low impedance path
when off. An active high output, resistor, and small signal
diode provide an excellent LED driver. This circuit is shown in
Figure 32.

UNDERVOLTAGE LOCKOUT
It is desirable to protect an IGBT from insufficient gate
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.
The MC33153 will typically start up at about 12 V. The
UVLO circuit has about 1.0 V of hysteresis and will disable
the output if the supply voltage falls below about 11 V.
