Advance Information
Single IGBT High Current
Gate Driver
The MC33154 is specifically designed as an IGBT driver for high powered
applications including ac induction motor control, brushless dc motor control,
and uninterruptable power supplies. This device also offers a cost effective
solution for driving power MOSFETS and Bipolar transistors.
Device protections include the choice of desaturation or overcurrent
sensing and an undervoltage lockout to provide assurance of proper gate
drive voltage.
These devices are available in dual–in–line and surface mount packages
and include the following features:
• High Current Output Stage: 4.0 A Source –2.0 A Sink
• Protection Circuits for Both Conventional and Sense IGBT’s
• Current Source for Blanking Timing
• Protection Against Over–Current and Short Circuit
• Under–Voltage Lockout Optimized for IGBT’s
• Negative Gate Drive Capability

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 overcurrent sense.
The blanking pin should never be tied high. That would short
out the internal IC clamp transistor.
