Abstract

An undervoltage-lockout circuit is provided. The undervoltage-lockout circuit includes a current mirror circuit, a current source, a first reference transistor, a second reference transistor, and a comparison circuit. The current mirror circuit includes a first connection terminal and a second connection terminal. The current source is coupled to the first connection terminal. A first terminal of the first reference transistor is coupled to the second connection terminal. A second terminal of the first reference transistor provides a reference voltage. A first terminal of the second reference transistor is coupled to the second terminal of the first reference transistor. A second terminal of the second reference transistor is coupled to a system low voltage. The comparison circuit receives an input voltage at the first connection terminal and the reference voltage. The comparison circuit generates an undervoltage-lockout signal according to the input voltage and the reference voltage.
