Abstract

A voltage state detector includes an input terminal, a voltage drop circuit, a pull-down circuit, a load circuit, a transistor, a pull-up circuit, a first output terminal, and a second output terminal. The voltage drop circuit is coupled to the input terminal. The pull-down circuit is coupled to the voltage drop circuit and a first reference terminal. The load circuit is coupled to a second reference terminal. The transistor has a first terminal coupled to the load circuit, a second terminal coupled to the first reference terminal, and a control terminal coupled to the voltage drop circuit. The pull-up circuit is coupled to the second reference terminal 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.
