Abstract
A low-voltage detection circuit detects a terminal voltage of a power supply terminal. The low-voltage detection circuit includes a first voltage-dividing circuit, a second voltage-dividing circuit, and a comparator. The second voltage-dividing circuit includes a bias circuit and a metal-oxide-semiconductor (MOS) transistor. The comparator compares and receives a voltage generated by the first voltage-dividing circuit and a voltage generated by the second voltage-dividing circuit to generate a voltage detection signal.
