Alps Alpine has added two new products to its magnetic sensor lineup to support the ongoing electrification of vehicles. This builds on a track record in the automotive market in the areas of steering angle detection and electronic shifters.
Redundancy design is increasingly a requirement for automobile driving systems as the world looks to embrace driving assistance and autonomous vehicles. The use of multiple sensors was once the typical way of realizing redundancy, to ensure that systems function safely even when a fault occurs. In recent years, however, smaller systems more often mean fewer parts and therefore greater demand for angle sensors that achieve redundancy by providing two output signals from a single product.
Alps Alpine’s new magnetic sensors have a built-in amp to support size reductions and fulfill redundancy design needs with single-ended high output of 3Vpp. The dual-die1 model meets requirements for full redundancy design and can be supplied as a single product. Envisaged for use in automotive motors, the magnetic sensors can be used to create conditions resilient against outside magnetic disturbance. This is because they perform well in high-temperature environments up to 150°C while also achieving strong magnetic field resistance of 120mT through application of original thin-film technology.
The magnetic sensors are being mass produced with applications envisaged in automotive motors and 15 million units are expected to be sold in 2030.
Alps Alpine will also further pursue development of smaller, low-cost magnetic sensors resistant to outside magnetic disturbance.
Alps Alpine develops and manufactures sensors for a wide range of applications in consumer products like smartphones through to automotive electronics. Seeking to contribute to society through our business, we will keep striving to develop products best matching the needs of customers and the market.
