Infineon SBS User manual

Product Safety Warnings
The Smart Battery Switch (SBS) is only intended to be used as an engineering demon-
strator. It is not intended for extensive use or to be re-used in a product or system that is
sold to consumers.
The SBS is intended to be used by electrical engineers who are experts in the field of
high current design. If you are not qualified, seek the help of an expert before using the
demonstrator.
Questions about the SBS should be directed to Infineon Application Engineering.
The cable, cable lug, washer and nut used to connect to the bolt mounted onto the SBS
demonstrator’s circuit board must all be made of high current-capable metals which will
not experience a significant temperature rise while conducting the current.
Battery Camping compliant to IEC 60095-2_Ed.4 (2009)
The cable lug must be mounted directly to the bolt (torque 6Nm ±1Nm).
Keep the current below 1800 A. The time a current may be applied is limited by
the temperature rise.
Don‘t exceed 1 Joule of switching energy.
Switching to high currents or to high switch o energy may destroy the switch and
the test setup and end up in fire.
