Infineon Technologies AG Magnetic position sensors, 3D magnetics TLE493D-W2B6 A1

XENSIV™ - TLE493D-W2B6 A1 3D magnetic sensor with enhanced dynamic wake up-feature

With the TLE493D-W2B6 A0-A3, a 3D sensor has been developed, which includes an enhanced dynamic wake up feature. Four pre-programmed address options (A0-A3) will be available, enabling for a fast start up initialization, when used in I2 C bus configurations. It also includes enhanced test options and a safety documentation is available to enable the usage of this sensor in the context of ASIL B systems.

By combining 3-axis measurement in a small package, with low power consumption, the 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 I2C 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.
