Definition
Please consult the most recently issued document before initiating or
completing a design.
The term 'short data sheet' is explained in section "Definitions".
The product status of device(s) described in this document may have
changed since this document was published and may differ in case of
multiple devices. The latest product status information is available on
the Internet at URL http://www.ween-semi.com.
Definitions
Draft — The document is a draft version only. The content is still under

Product specification — The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
WeEn Semiconductors and its customer, unless WeEn Semiconductors and
customer have explicitly agreed otherwise in writing. In no event however,
shall an agreement be valid in which the WeEn Semiconductors product
is deemed to offer functions and qualities beyond those described in the
Product data sheet.
Disclaimers
Limited warranty and liability — Information in this document is believed to
be accurate and reliable. However, WeEn Semiconductors does not

notice. This document supersedes and replaces all information supplied prior
to the publication hereof.
Suitability for use — WeEn Semiconductors products are not designed,
authorized or warranted to be suitable for use in life support, life-critical
or safety-critical systems or equipment, nor in applications where failure
or malfunction of an WeEn Semiconductors product can reasonably
be expected to result in personal injury, death or severe property or
environmental damage. WeEn Semiconductors and its suppliers accept no
liability for inclusion and/or use of WeEn Semiconductors products in such
equipment or applications and therefore such inclusion and/or use is at the
customer’s own risk.
Quick reference data — The Quick reference data is an extract of the
product data given in the Limiting values and Characteristics sections of this
document, and as such is not complete, exhaustive or legally binding.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. WeEn Semiconductors makes
no representation or warranty that such applications will be suitable for the
specified use without further testing or modification.
Customers are responsible for the design and operation of their applications
and products using WeEn Semiconductors products, and WeEn
Semiconductors accepts no liability for any assistance with applications or
customer product design. It is customer’s sole responsibility to determine
whether the WeEn Semiconductors product is suitable and fit for the
customer’s applications and products planned, as well as for the planned
application and use of customer’s third party customer(s). Customers should
provide appropriate design and operating safeguards to minimize the risks
associated with their applications and products.
WeEn Semiconductors does not accept any liability related to any default,
damage, costs or problem which is based on any weakness or default
in the customer’s applications or products, or the application or use by
customer’s third party customer(s). Customer is responsible for doing all
necessary testing for the customer’s applications and products using WeEn
Semiconductors products in order to avoid a default of the applications
and the products or of the application or use by customer’s third party
customer(s). WeEn does not accept any liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those
given in the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
No offer to sell or license — Nothing in this document may be interpreted
or construed as an offer to sell products that is open for acceptance or the
grant, conveyance or implication of any license under any copyrights, patents
or other industrial or intellectual property rights.
Export control — This document as well as the item(s) described herein
may be subject to export control regulations. Export might require a prior
authorization from competent authorities.
Non-automotive qualified products — Unless this data sheet expressly
states that this specific WeEn Semiconductors product is automotive
qualified, the product is not suitable for automotive use. It is neither qualified
nor tested in accordance with automotive testing or application requirements.
WeEn Semiconductors accepts no liability for inclusion and/or use of nonautomotive qualified products in automotive equipment or applications.
In the event that customer uses the product for design-in and use in
automotive applications to automotive specifications and standards,
customer (a) shall use the product without WeEn Semiconductors’ warranty
of the product for such automotive applications, use and specifications, and
(b) whenever customer uses the product for automotive applications beyond
WeEn Semiconductors’ specifications such use shall be solely at customer’s
own risk, and (c) customer fully indemnifies WeEn Semiconductors for
any liability, damages or failed product claims resulting from customer
design and use of the product for automotive applications beyond WeEn
Semiconductors’ standard warranty and WeEn Semiconductors’ product
specifications.
