Linear Hall IC
are programmable analog/digital sensors for highly accurate angular and linear position detection
Our TLE499x linear Hall ICs familly 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 ratiometric analog output. They are available in leaded packages, as well as 1 mm-thick dual- or single-sensor SMD packages.
Two sensors in one SMD package for automotive applications
Infineon´s new SMD package (TDSO) includes two independent sensors with separate power supply and separate signal outputs. Due to special mounting technology, Infineon is able to keep dual-sensor package size very small to enable compact PCB layouts and small magnet sizes. We offer a wide range of Hall sensors in the TDSO package. The two sensors in one package offer sensor redundancy in one package. Sensor redundancy is especially interesting for new generation EPS steering systems with increased ISO 26262 requirements and other safety critical applications. All sensors are automotive qualified. Most products are also available as single-sensor solution with only one sensor.
