Monolithic IC PST70XX Series
Outline
These low reset type ICs function 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. They are ideal for use in battery check circuits for products using batteries, as they have ultra-low current consumption and a high precision
voltage detection function.
