This closes the circuit and turns the transistor on. Apply the opposite charge and the electrode flips back, breaking the circuit.

为管理芯片产生复位输入，其输入必须接收低有效的地信号，需要晶体管q 1导通。
To create an reset input to the supervisory chip, its input must receive an active-low ground signal, requiring transistor Q1 to turn on.

通过给晶体管增加一些电容、二极管和电阻，使用保持时间可调的复位IC，将纯手动复位转换为自动复位。
By adding a transistor with some capacitors, diodes, and resistors, you can transform a pure-manual reset to an automatic reset with adjustable hold time for the reset IC.
