    • A electronic device includes an electrical component powered by a battery and a compartment to receive the battery. A low voltage cutoff circuit is configured to couple to the battery. The low voltage cutoff circuit includes a switching device having a control terminal, a current sourcing terminal and current sinking terminal and a resistor coupled between the control terminal and a first terminal of a battery. The circuit has first and second output terminals. The first output terminal is coupled to the first terminal of the battery and the second output terminal is coupled to the current sourcing terminal of the transistor. The first and second output terminals are configured to accept connections to positive and negative terminals of the electrical component.
    • 电子设备包括由电池供电的电气部件和用于接收电池的隔室。 低电压切断电路被配置为耦合到电池。 低压截止电路包括具有控制端子,电流源端子和电流吸收端子以及耦合在控制端子与电池的第一端子之间的电阻器的开关装置。 该电路具有第一和第二输出端子。 第一输出端子耦合到电池的第一端子,第二输出端子耦合到晶体管的电流源端子。 第一和第二输出端子被配置为接受与电气部件的正端子和负极端子的连接。
