General Description

The HT70XX series is 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 7V. The voltage de-

tectors consist of a high-precision and low power con-

sumption standard voltage source, a comparator,

hysteresis circuit, and an output driver. CMOS technol-

ogy 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 (NMOS open

drain type only).
