Our family of TLE499x linear Hall ICs is tailored to the needs of highly accurate angular and linear position detection and current measurement applications.
Each product measures the vertical component of a magnetic field and outputs a signal that is directly proportional to the magnetic field. These programmable linear Hall sensors come with different interface options
- TLE4997 features radiometric analog output while
- TLE4998P comes with pulse width modulation (PWM)
- TLE4998S with single edge nibble transmission (SENT) and
- TLE4998C with short PWM codes (SPC)
Dual-sensor package for functionally safe systems-angle and linear Hall
Infineon´s latest SMD package (PG-TDSO) includes two redundant sensors in the place of one with independent power supply and separate signal outputs.
Due to special mounting technology, we can keep our dual-sensor package size very small to enable compact PCB layouts and small magnet sizes.The two sensors in one package offer inherent redundancy.
In addition TLE 5309D provides diversity due to the use of one iAMR and one iGMR sensor.
Sensor redundancy is of particular interest for new generation EPS steering systems with highest ASIL requirements and other safety critical applications.

These high-precision 12-bit resolution linear Hall sensors feature EEPROM memory for flexible programming across a wide range of parameters.
Thanks to digital signal processing based on a 20-bit DSP architecture plus digital temperature compensation, these sensors deliver outstanding temperature stability compared with similar compensation methods.
TLE4998 also includes stress compensation to withstand stress effects from the package, such as moisture, thus ensuring best-in-class accuracy over the device’s lifetime.
