Description
The AUIR3320(S) is a fully protected 4 terminals high side
switch. The input signal is referenced to Vcc. When the
input voltage Vcc - Vin is higher than the specified
threshold, the output power Mosfet is turned on. When the
Vcc - Vin is lower than the specified Vil threshold, the
output Mosfet is turned off. A current proportional to the
power Mosfet current is sourced to the Ifb pin. Over
current shutdown occurs when Vifb-Vin > 4.7V. The
current shutdown threshold is adjusted by selecting the
proper RIfb. Either over current and over temperature
latches off the switch. The device is reset by pulling the
input pin high. Other integrated protections (ESD, reverse
battery, active clamp) make the switch very rugged in
automotive environment.

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.
