Magnetic angle sensors are high precision, high output for automotive market
High-precision, high-output magnetic angle sensors for automotive motors have been added to Alps Alpine’s magnetic sensor range to support the ongoing electrification of vehicles.
Redundancy design is increasingly a requirement for automobile driving systems. Conventionally, multiple sensors were the typical way of realising redundancy, to ensure that systems function safely even when a fault occurs. Recently, smaller systems mean fewer parts and therefore greater demand for angle sensors that achieve redundancy by providing two output signals from a single product, explained Alps Alpine.
The 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-die model meets requirements for full redundancy design and can be supplied as a single product.
The magnetic sensors can be used to create conditions resilient against outside magnetic disturbance to perform in high temperature environments up to 150°C while also achieving strong magnetic field resistance of 120mT. This is achieved through application of original thin film technology, confirmed Alps Alpine.
The magnetic sensors can be used in automotive motors, electric power steering system motors and main motors. The company announced that it will also pursue development of smaller, low cost magnetic sensors resistant to outside magnetic disturbance.
The HGARPS001A (dual-die) sensor provides four analogue output signals and has an operating temperature range of -40 to +150°C for automotive use. The sensor meets the AEC-Q100 automotive reliability standard.
The HGARPS011A (single-die) sensor (pictured) has a high output achieved with dual signal output and a built-in amp (3Vpp single-ended at VDD of 5V).
It has the same operating temperature and also meets the AEC-Q100 automotive reliability standard.
Alps Alpine, Alps Electric and Alpine Electronics integrated their businesses and became Alps Alpine, delivering products for the automotive market, but also mobile devices and consumer electronics, as well as new sectors such as energy, healthcare and industry.
Since 2013, the company’s European head office has been located in Munich, co-ordinating sales, marketing and product engineering activities of offices in Dusseldorf, Stuttgart, Wolfsburg, Paris, Milton Keynes, Frolunda and Milan, as well as the production activities of a manufacturing site in Dortmund, Germany.
