摘要： A self-loop detection method and apparatus for a charging device (3) relating to the field of circuit technologies are disclosed, so as to detect, when the charging device (3) performs inbound charging and outbound charging at the same time, whether a self-loop exists in the charging device (3). The self-loop detection method for a charging device (3) includes: switching the positive signal cable D o and the negative signal cable D o from a connected state to a disconnected state; and detecting whether the positive signal cable D i and the negative signal cable D i are switched from a connected state to a disconnected state; and if yes, determining that a self-loop exists in the charging device (3). According to the self-loop detection method for a charging device (3), whether a self-loop exists in the charging device (3) may be detected when the charging device (3) performs inbound charging and outbound charging at the same time.

摘要： This application provides an electronic device and a control method for a movable assembly. The electronic device provided in this application includes a movable assembly. An optical proximity sensor is disposed on the movable assembly. The movable assembly may be spaced from a fixed assembly on the electronic device, and the movable assembly can move on a plane that is disposed in parallel relative to the fixed assembly. A light intensity of light that is from the optical proximity sensor and that is reflected by the fixed assembly may reflect a position of the movable assembly relative to the fixed assembly. According to the control method for a movable assembly in this application, whether the movable assembly moves to a specified target position may be determined based on the light intensity of the light that is reflected by the fixed assembly and that is detected by the optical proximity sensor.

摘要： A current-limiting protection circuit (101) and an electronic device (100) are provided. The current-limiting protection circuit includes: a power supply chip (21) and a current-limiting circuit that is electrically connected to the power supply chip. The current-limiting circuit is configured to: detect a charging current, and output a feedback voltage to the power supply chip. The power supply chip is configured to: when the feedback voltage is greater than a second reference voltage, reduce an output voltage until the charging current reaches a preset value, where the second reference voltage is a preset internal voltage of the power supply chip.
