Dual Channel High Speed Low
Side Driver, AUIRS4427S
The AUIRS4427S is a low voltage, high speed power
MOSFET and IGBT driver. Proprietary latch immune
CMOS technologies enable ruggedized monolithic
construction. The logic input is compatible with
standard CMOS or LSTTL output. The output drivers
feature a high pulse current buffer stage designed for
minimum driver cross-conduction. Propagation
delays between two channels are matched.
Gate drive supply range from 6V to 20V
CMOS Schmitt-triggered inputs
3.3V and 5V logic compatible
Two independent date drivers
Matched propagation delay for both
• Outputs in phase with inputs
• Lead-free, RoHS compliant
• Automotive qualified according to AECQ100
• Proprietary HVIC technology enables ruggedized monolithic
construction and an industry benchmarking negative voltage spike
immunity for fail proof operation even under extreme switching
conditions and short circuit events.
• The IC is qualified according to AEC-Q100 standards and features
an environmentally friendly, lead-free and RoHS compliant bill of
material and is part of International Rectifier’s Zero-Defect initiative.
• The AUIRS4427S is a very rugged, general purpose dual channel
low side driver which was specifically designed, tested and
qualified for use in harsh environments such as automotive underthe-hood applications.
