Infineon Technologies AG introduces the new XENSIV TLE49SR angle sensor family, which combines excellent stray field immunity with high accuracy.

The sensors are ideal for applications of safety-critical automotive chassis systems such as electric power steering and vehicle height levelling.

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 hybridisation and electrification with 4,000A/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 with less than 1°. By using a look-up table, the angle error can be reduced even further: Multi point calibration (16 variable and 32 equidistant) results in an angle error below 0.5°. This feature helps to compensate angle deviations resulting e.g., from mechanical misalignments of the manufacturing process.

The 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.

Availability

The first products of the new XENSIV TLE49SR angle sensor family are available now with either PWM, SENT, or SPC interface. For surface mounting, they are supplied in a TDSO-8 package.
