AUIRS44261S
Description
The AUIRS44261 is a low voltage, high speed power MOSFET and IGBT driver. Proprietary latch immune
CMOS technologies enable ruggedized monolithic construction. The logic inputs thresholds are proportional
to Vs supply voltage.. The output drivers feature a high pulse current buffer stage designed for minimum
driver cross-conduction. Propagation delays between two channels are matched.

Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage
parameters are absolute voltages referenced to GND lead. Stresses beyond those listed under "
Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only; and
functional operation of the device at these or any other condition beyond those indicated in the “Recommended
Operating Conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may
affect device reliability. The thermal resistance and power dissipation ratings are measured under board mounted
and still air conditions. Ambient temperature (TA) is 25°C, unless otherwise specified.

Parameter Trends vs. Temperature
Figures illustrated in this chapter provide information on the experimental performance of the AUIRS44261S HVIC.
The line plotted in each figure is generated from actual lab data. A large number of individual samples were tested at
three temperatures (-40 ºC, 25 ºC, and 125 ºC) with supply voltage of 15V in order to generate the experimental
curve. The line consists of three data points (one data point at each of the tested temperatures) that have been
connected together to illustrate the understood trend. The individual data points on the Typ. curve were determined
by calculating the averaged experimental value of the parameter (for a given temperature).

IMPORTANT NOTICE
Unless specifically designated for the automotive market, International Rectifier Corporation and its subsidiaries
(IR) reserve the right to make corrections, modifications, enhancements, improvements, and other changes to
its products and services at any time and to discontinue any product or services without notice. Part numbers
designated with the “AU” prefix follow automotive industry and / or customer specific requirements with regards
to product discontinuance and process change notification. All products are sold subject to IR’s terms and
conditions of sale supplied at the time of order acknowledgment.
IR warrants performance of its hardware products to the specifications applicable at the time of sale in
accordance with IR’s standard warranty. Testing and other quality control techniques are used to the extent IR
deems necessary to support this warranty. Except where mandated by government requirements, testing of all
parameters of each product is not necessarily performed.
IR assumes no liability for applications assistance or customer product design. Customers are responsible for
their products and applications using IR components. To minimize the risks with customer products and
applications, customers should provide adequate design and operating safeguards.
Reproduction of IR information in IR data books or data sheets is permissible only if reproduction is without
alteration and is accompanied by all associated warranties, conditions, limitations, and notices. Reproduction
of this information with alterations is an unfair and deceptive business practice. IR is not responsible or liable
for such altered documentation. Information of third parties may be subject to additional restrictions.
Resale of IR products or serviced with statements different from or beyond the parameters stated by IR for that
product or service voids all express and any implied warranties for the associated IR product or service and is
an unfair and deceptive business practice. IR is not responsible or liable for any such statements.
IR products are not designed, intended, or authorized for use as components in systems intended for surgical
implant into the body, or in other applications intended to support or sustain life, or in any other application in
which the failure of the IR product could create a situation where personal injury or death may occur. Should
Buyer purchase or use IR products for any such unintended or unauthorized application, Buyer shall indemnify
and hold International Rectifier and its officers, employees, subsidiaries, affiliates, and distributors harmless
against all claims, costs, damages, and expenses, and reasonable attorney fees arising out of, directly or
indirectly, any claim of personal injury or death associated with such unintended or unauthorized use, even if
such claim alleges that IR was negligent regarding the design or manufacture of the product.
Only products certified as military grade by the Defense Logistics Agency (DLA) of the US Department of
Defense, are designed and manufactured to meet DLA military specifications required by certain military,
aerospace or other applications. Buyers acknowledge and agree that any use of IR products not certified by
DLA as military-grade, in applications requiring military grade products, is solely at the Buyer’s own risk and
that they are solely responsible for compliance with all legal and regulatory requirements in connection with
such use.
IR products are neither designed nor intended for use in automotive applications or environments unless the
specific IR products are designated by IR as compliant with ISO/TS 16949 requirements and bear a part
number including the designation “AU”. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, IR will not be responsible for any failure to meet such requirements.
