Abstract
A power-on detector supplied with a power supply voltage from an external source and detects a variation of the power supply voltage. The operating method of the power-on detector comprises calculating the slope of the rise of power supply voltage from a first voltage to a second voltage higher than the first voltage; and calculating the expected time for the power supply voltage to reach a target voltage level, based on the calculated slope.
