Abstract
An integrated circuit (IC) includes a reference voltage generator, a voltage regulator, a reset controller, and a voltage monitoring circuit. The reference voltage generator generates first and second reference voltages, and the voltage regulator generates a supply voltage. The reset controller stabilizes the first and second reference voltages in a first predetermined time period, and generates a power down signal after the first predetermined time period. The voltage monitoring circuit compares a level of the supply voltage with a level of the second reference voltage after the first predetermined time period and generates a (low) voltage monitor signal. The reset controller also generates a (high) reset signal when the supply voltage is greater than the second reference voltage.
