A voltage detection circuit for detecting the voltage level of a first power source. A first transistor includes a first gate, a first source, and a first drain coupled to the first gate. A second transistor includes a second gate, a second source, and a second drain coupled to the second gate. A comparator includes a first input terminal, a second input terminal coupled to the second drain, and an output terminal. A first resistor is coupled between the first input terminal and the first drain. A second resistor is coupled to the first power source. A third resistor is coupled between the second resistor and the first input terminal. A fourth resistor is coupled between the second resistor and input terminal. A fifth resistor is coupled between the first source, and a second power source. A resistive device is coupled between the first source, and the first power source.
