Description
The AUIRS2127S/AUIRS2128S/AUIRS21271S/AUIRS21281S are high voltage, high speed power MOSFET and
IGBT drivers. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction.
The logic input is compatible with standard CMOS or LSTTL outputs, down to 3.3 V. The protection circuitry detects
over-current in the driven power transistor and terminates the gate drive voltage. An open drain FAULT signal is
provided to indicate that an over-current shutdown has occurred. The output drivers feature a high pulse current
buffer stage designed for minimum cross-conduction. The floating channel can be used to drive an N-channel
power MOSFET or IGBT in the high- side or low-side configuration which operates up to 600 V.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which permanent damage to the device may occur.
These are stress ratings only, functional operation of the device at these or any other condition beyond those
indicated in the Recommended Operating Condition” is not implied. Exposure to absolute maximum-rated
conditions for extended periods may affect device reliability. All voltage parameters are absolute voltages
referenced to COM unless otherwise stated in the table. The thermal resistance and power dissipation ratings are
measured under board mounted and still air conditions.
Recommended Operating Conditions
The input/output logic timing diagram is shown in Fig. 1. For proper operation the device should be used within the
recommended conditions. The V
S
offset rating is tested with all supplies biased at 15 V differentials.
Logic operational for V
S
of -5 to +600 V. Logic state held for V
S
of -5 V to – V

Parameter Temperature Trends
Figures 6-33 provide information on the experimental performance of the AUIRS212(7, 71, 8, 81)S 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) in order to
generate the experimental curves. 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 curve were determined by calculating the averaged experimental value of the parameter (for a given
temperature).
A different set of individual samples was used to generate curves of parameter trends vs. supply voltage.

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.
IR products are neither designed nor intended for use in military/aerospace applications or environments unless the IR
products are specifically designated by IR as military-grade or “enhanced plastic.” Only products designated by IR as
military-grade meet military specifications. Buyers acknowledge and agree that any such use of IR products which IR has
not designated as military-grade is solely at the Buyer’s 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.
