Abstract
A voltage state detector includes a voltage drop circuit, a pull-down circuit, a load circuit, a transistor, a pull-up circuit, first and second output terminals, and a logic circuit. The pull-down circuit is coupled to the voltage drop circuit. The transistor has a first terminal coupled to the load circuit, a second terminal coupled to the pull-down circuit, and a control terminal coupled to the voltage drop circuit. The pull-up circuit is coupled to the load circuit and the voltage drop circuit. The first output terminal is coupled to the first terminal of the transistor for outputting a first state determination signal. The second output terminal is coupled to the voltage drop circuit for outputting a second state determination signal. The logic circuit includes a NOR gate for performing an NOR operation on the first state determination signal and the second state determination signal to output a control signal.
