In one implementation, the first electronic switch 102 may be a PMOS transistor, and the second electronic switch 103 may be an NMOS transistor, although other electronic switches, such as a triode, an IGBT transistor, etc., may be used, which is not limited herein.
In the application, an MOS transistor is taken as an example, and the controller 104 provided in the application may adopt an MCU, when the MCU obtains an off instruction, a low-level driving signal is output, the level of the cutoff_bat port in the figure is pulled down, the gate level of the second electronic switch 103 is pulled down, and at this time, the second electronic switch 103 is in an off state; when the second electronic switch 103 is turned off, the gate of the first electronic switch 102 is connected to a high level, which is also in an off state, and at this time, the battery 101 cannot supply voltage to the electronic components at the rear stage, and the connection between the built-in battery 101 and the circuit board is disconnected.
