Infineon's AMR-Based Angle Sensors Tout Angle Accuracy at Low Magnetic Fields
June 28, 2019
Infineon Technologies XENSIV TLE5109A16 AMR-based angle sensors address the need for very precise, fast and yet cost-efficient angle measurement.
Infineon Technologies XENSIV TLE5109A16 AMR-based angle sensors address the need for very precise, fast and yet cost-efficient angle measurement at the highest functional safety levels in automotive and industrial applications. The new devices are designed for 180° angle measurement but are also applicable for 360° measurement in motors with an even number of pole pairs. They are suitable for a broad range of magnetic fields, starting at 10 mT reaching up to more than 500 mT.
Device accuracy typically exhibits angle error values of 0.1°. Especially at low magnetic fields between 10 and 20 mT, where usually the angle error significantly increases, XENSIV TLE5109A16 products outperform current solutions on the market by achieving angle errors as low as 0.2°. This enables cost-efficient system solutions as it allows customers to use less powerful and thus cheaper magnets.
XENSIV TLE5109A16 products are available as single and dual die versions, the latter suitable for ASIL D level safety applications. Infineon is offering the devices with two different supply voltage options: 3.3 V and 5 V. The sensors’ short start-up time of 40 to 70 µs outperforms the legacy solutions.
