IC for System Reset

Monolithic IC PST70XX Series

May 21, 2002

Outline

This IC is a low-reset type system reset IC and in a variety of CPU systems and other logic systems, to detect

supply voltage and reset the system accurately when the power is turned on or interrupted.

It includes a high-precision voltage detection function with ultra-low current consumption and is ideal for

voltage check circuits for products using a battery.

Features

1. High-precision voltage detection

±. Ultra-low current consumption
