Outline

This IC functions in a variety of CPU systems and other logic systems, to detect power supply voltage and reset the system accurately when power is turned on or interrupted. This ultra-low current consumption low reset type system reset IC has a built-in delay time generating circuit that can set the time by an external capacitor and resistor. It is ideal for use in multi-CPU systems because a fast-rising output waveform can be obtained.
