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).
