Alps Alpine Co., Ltd. has added two new products to its magnetic sensor lineup to support the ongoing electrification of vehicles.
High output achieved with a built-in amp (3Vpp single-ended @VDD=5V)
Four analog output signals (+sin, +cos, -sin, -cos) × 2 circuits
Operating temperature range for automotive use: -40°C to +150°C
Meets AEC-Q100 automotive reliability standard
High output achieved with dual signal output and a built-in amp (3Vpp single-ended @VDD=5V)
Four analog output signals (+sin, +cos, -sin, -cos)
Operating temperature range for automotive use: -40°C to +150°C
Meets AEC-Q100 automotive reliability standard
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-die 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.
