Applications

General Description

The H70XXA-1 series devices are a set of three

terminal low power voltage detectors implemented

in CMOS technology. Each voltage detector in the

series detects a particular fixed voltage ranging

from 2.2V to 7.0V. The voltage detectors consist of

a high-precision and low power consumption

standard voltage source as well as a comparator,

hysteresis circuit, and an output driver. CMOS

technology ensures low power consumption.

Although designed primarily as fixed voltage

detectors, these devices can be used with external

components to detect user specified threshold

voltages.
