摘要:
The present teaching relates to a magnetic sensor (1105) including an input port (1102, 1104) and an output port (1106) and an electrical circuit (1100) which includes a magnetic field detecting circuit (1130), an output control circuit (1120), a state control circuit (1140) coupled with the output control circuit (1120) and configured to determine whether a predetermined condition is satisfied and signal the same to the output control circuit (1120). When the predetermined condition is satisfied, the state control circuit (1140) is at least responsive to the magnetic induction signal to enable the output control circuit (1120) to control the magnetic sensor to operate in at least one of a first state and a second state. In the first state, a load current flows in a first direction from the output port (1106) to outside of the magnetic sensor. In the second state, a load current flows in a second direction opposite of the first direction from outside of the magnetic sensor into the magnetic sensor via the output port (1106). When the predetermined condition is not satisfied, the state control circuit (1140) enables the output control circuit (1120) to control the magnetic sensor to operate in a third state.

A motor assembly, an integrated circuit and an application device including the motor assembly are provided. The motor assembly includes a motor (100) and a motor driving circuit (200), the motor driving circuit (200) includes a step down circuit (10), and the step down circuit (10) includes a first current branch and a second current branch which are turned on selectively. The step down circuit can be integrated in an application specific integrated circuit to reduce the complexity and cost of the circuit.

A magnetic sensor integrated circuit (400) and a motor assembly are provided. The integrated circuit includes a housing (2), a semiconductor substrate arranged in the housing, at least one input port (A1, A2) and an output port (Pout), and an electronic circuit arranged on the semiconductor substrate. The electronic circuit includes a rectifying circuit (60), a magnetic field detection circuit (20) configured to detect an external magnetic field and output magnetic field detection information, and an output control circuit (20) connected to the rectifying circuit (60) and configured to control, at least based on the magnetic field detection information, the integrated circuit to operate in at least one of a first state in which a load current flows from the output port (Pout) to an outside of the integrated circuit and a second state in which a load current flows from the outside of the integrated circuit to the output port (Pout). The load current flows through the rectifying circuit (60).
