Magnetic sensor integrated circuit, motor component and application apparatus
First Claim
1. A magnetic sensor integrated circuit, comprising:
- at least one input port and one output port;
a magnetic field detection circuit configured to detect an external magnetic field and output magnetic field detection information accordingly; and
an output control circuit configured to selectively enable a load current flowing out to an outside of the integrated circuit from the one output port and the load current flowing into the one output port to a ground in the integrated circuit from the outside of the integrated circuit; and
wherein the output control circuit outputs a control signal to a controllable bidirectional AC switch, the controllable bidirectional AC switch is controlled to be switched between a switch-on state and a switch-off state in a predetermined way; and
the output control circuit comprises a first current path in which a current flows out from the output port, a second current path in which a current flows in from the output port, and a switch connected in one of the first current path and the second current path, wherein the switch is controlled by the magnetic field detection information outputted by the magnetic field detection circuit, and allows the first current path and the second current path to be selectively turned on.

Abstract
A magnetic sensor integrated circuit, a motor component and an application apparatus are provided. The integrated circuit includes: an input port, an output port, a magnetic field detection circuit and an output control circuit. The magnetic field detection circuit detects an external magnetic field and outputs magnetic field detection information. The output control circuit enables, at least based on the magnetic field detection information, the integrated circuit to switch at least between a first state, in which a current flows from the output port to an outside of the integrated circuit, and a second state, in which a current flows from the outside of the integrated circuit to the output port.
