The sensor features contactless 360 degrees sensing within a temperature range of -40 °C to +150 °C. In comparison with conventional resolver-based solutions, the TDK device is lighter and requires significantly less space.
Another unique feature is the automatic correction function that considerably reduces the design-in effort. Moreover, the new angle sensor is equipped with a self-diagnostic function that detects not only an abnormality in the sensor itself, but also any abnormalities in the exterior environment, such as a power failure or loss of the magnetic field. Thanks to the integrated ASIC, this sensor is capable of digital output with all kinds of interfaces, such as SPI, Hall sensor emulation (HSM), PWM and encoder (AZB). It uses the ASIC design technology from ICsense, an ASIC design specialist, which TDK acquired in March 2017. Based on this technology combination TDK can offer modular sensor solutions, including ASICs.
Besides automotive applications - with particular focus on applications for automated driving – the TAD2141 suits for industrial and robotics applications. TDK intends to further extend the range of possible applications in the future.
Engineering samples of TAD2141 are already available; while certifications according to ISO26262 and ASIL are under preparation.
