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 (T_A) 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).

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

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.

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.
