Infineon Technologies AG has introduced the new XENSIV TLE49SR angle sensor family, which combines excellent stray field immunity with high accuracy. These sensors are ideal for applications of safety-critical automotive chassis systems such as electric power steering and vehicle height leveling.
All products in the XENSIV TLE49SR family withstand stray magnetic fields of up to 8mT. The sensors exceed the requirements of ISO11452-8 level IV for car hybridization
and electrification with 4000A/m (equal to 5mT) for inhomogeneous stray field and eliminate the need for external shielding.
The intrinsic accuracy of the sensors defines an angle error ess than 1°. By using a look-up table, the angle error can be reduced even further. These angle sensors were developed according to ISO 26262 as a “safety element out of context.” The ASIL C metric on component level enables system designs up to functional safety level ASIL D.
