Patent number: 10759276Abstract: A magnetic sensor includes a magneto-resistive element, a Hall element, and a detection circuit that receives a signal from the magneto-resistive element and a signal from the Hall element input thereto. The detection circuit includes an output terminal and an interrupt generation unit. The output terminal outputs, to the outside as an output signal, a signal obtained by performing to the signal input from the magneto-resistive element, at least one processing selected from amplification, analog-to-digital conversion, offset correction, and temperature-characteristics correction. The interrupt generation unit outputs an interrupt signal when the signal input from the Hall element is larger than a predetermined threshold. The magnetic sensor is high accurate and highly reliable.Type: GrantFiled: June 27, 2017Date of Patent: September 1, 2020Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Kazuhiro Onaka, Shigehiro Yoshiuchi, Noritaka Ichinomiya, Kiyotaka Yamada
