  • Hall element driving circuit, sensor circuit, and current measuring apparatus
    Patent number: 10386392
    Abstract: A Hall element driving circuit includes: a signal switching unit which is disposed between a power supply, which outputs a current, and a Hall element having first and second terminals and performs switching control between a first switching state that supplies the current to the first terminals and a second switching state that supplies the current to the second terminals; a switching control unit that controls transitions between the first switching state and the second switching state; and a switching unit that is disposed between the power supply and the signal switching unit and controls switching between an on state where the current is supplied and an off state where the current is stopped. The switching control unit controls transitions between the on and off states and executes switching control over the signal switching unit only when the switching unit is in the off state.
