Abstract: A power supply includes a battery and a shell configured to house the battery. The power supply also includes at least one detecting device configured to operably couple to the shell and including a movable member, a sensing assembly, and a first position limiting structure. The movable member is configured to movably couple with the first position limiting structure. The sensing assembly is configured to generate an indication signal for indicating whether the power supply has been mounted to at a mounting position of a battery compartment based on a location of the movable member. When the power supply is mounted at the mounting position, the movable member is moved to a location adjacent a first side of the first position limiting structure, and the sensing assembly generates a first indication signal for indicating that the power supply is mounted at the mounting position.

Abstract: A low-power-consumption high-speed zero-current switch includes a delay controller, a driving stage and a power transistor MN, wherein: an input of the delay controller is connected with an external clock CLK, an output of the delay controller is connected with an input of the driving stage, and an output of the driving stage is connected with a gate of the power transistor MN; the delay controller includes a gate signal generator, a sampling circuit and a current controller, and three of which form a negative feedback loop for stabilizing the turn-on voltage VON and the turn-off voltage VD to 0, so that when the power transistor MN is turned on or off, the source-drain voltage thereof is 0. The present invention no longer uses a high-power-consumption high-speed comparator, but uses a low-power-consumption delay controller to generate turn-on and turn-off signals of the power transistor.
