Infineon TLE493D - 3D magnetic sensor family

3D magnetic field sensor for smaller, more accurate and robust designs, ideal for automotive

Infineon 3D magnetic sensor

By combining 3-axis measurement in a small package, with low power consumption, Infineon’s TLE493D sensors provide a contactless position sensing alternative to applications which traditionally use mechanical or optical solutions. The system size for these applications can be reduced as magnetic threshold stability over temperature provides a highly accurate and more robust solution for those systems.

Infineon’s sensor provides a standard 2-wire digital I2 C communication interface, which enables a bi-directional communication between the sensor and microcontroller. In keeping with the highest quality standards and environmental regulations, the sensor is RoHs compliant, JESD47 or AEC-Q100 qualified and supports system according functional safety standard ISO 26262.

TLE493D-A2B6 is ideally suited for applications in the automotive area such as multi function steering wheel.

Key features
