Description
Our TLE499x linear Hall ICs family is the ideal choice for highly accurate angular and linear position detection and current measurement applications. Our sensors measure the vertical component of a magnetic field and outputs a signal that is directly proportional to the magnetic field. Infineon´s programmable linear Hall sensors come with different interface options PWM, SENT or SPC.
In the field of steering torque sensing, Infineon’s TLE499x series offers highly accurate linear Hall sensors for magnetic torque sensing assembly. In order to support a maximum of compatibility with various Electronic Control Unit (ECU) designs, the TLE499x sensors feature PWM, SENT, SPC or ratio metric analog output. They are available in leaded packages, as well as 1 mm-thick dual- or single-sensor SMD packages.
Our newest member in our broadest XENSIV™ magnetic position sensor portfolio is the world’s first fully ISO 26262-compliant linear Hall sensor for high precision applications. The TLE4999I3 is a dual channel linear Hall sensor with a synchronous digital PSI5-compatible interface, compliant to
ISO 26262, supporting safety requirements on system level rated up to ASIL D. Our linear Hall IC TLE4999I3 features two highly accurate Hall measurement channels on one chip. A plausibility check of the two redundant channels on system level enables a high diagnostic coverage. Highest accuracy over a wide temperature range and lifetime is achieved by an integrated digital temperature- and stress-compensation.
