Abstract

The application provides a driving circuit. The circuit includes: a segment display, including a plurality of light-emitting units; a controller, configured to generate a control instruction for the segment display according to a configuration signal; a digital driver, connected to the controller, and configured to generate a pulse driving signal according to the control instruction from the controller; and an amplification circuit, with one end being connected to the digital driver and the other end being connected to the plurality of light-emitting units of the segment display. The application also provides a magnetic sensing circuit and an electrical device. The magnetic sensing circuit includes a magnetic sensor, a sensing selection circuit, and a result representation circuit. A plurality of magnetic sensors are provided, and at least some of the plurality of magnetic sensors are capable of being connected to the sensing selection circuit by a sensing output terminal.
