ASIL D certification supporting angle sensor from TDK for automotive motors

High reliability sensor specialist TDK has launched a new less space occupying tiny tunnel magnetoresistance ( TMR) angle sensors TAS4240 targeting automotive motor applications such as Brushless DC (BLDC) and permanent-magnet synchronous motor (PMSM) commutation used in Electronic Power Steering, Brake booster of automotive vehicles. The sensor can also be used for industrial servo motors, automation, encoders, robotics. Available in compact TSSOP8 package with dimensions of 3 mm x 6.4 mm x 1.1 mm, TAS4240 provides two redundant analog single-ended SIN/COS outputs for extra safety. This high reliable sensor measures motor rotation angle precisely by taking very less space. TDK is presently sampling this device and production is expected to start in the month of April 2022. TAS4240 packs four TMR half bridges and provides two separated SIN/COS outputs. ASIL D certification of the system using this device is possible, where fail-operational concepts can also be supported by the sensor. TDK says this sensor also offers stable output even at different temperatures and over the sensor’s lifetime. The deterministic behavior of the TAS4240 in extended magnetic-field ranges opens up new application possibilities, even in demanding environments, as per the release by the company. Here below are some more key specifications, features, and benefits: Contactless 360° ...
