Product Summary
The HT7044A-1 is a set of three-terminal low power voltage detector implemented in CMOS technology. Each voltage detector in the series detects a particular fixed voltage ranging from 2.2V to 7V. The HT7044A-1 consists of a high-precision and low power consumption standard voltage source, a comparator, hysteresis circuit, and an output driver. CMOS technology ensures low power consumption. Although designed primarily as fixed voltage detectors, the HT7044A-1 can be used with external components to detect user specified threshold voltages (NMOS open drain type only). The applications of the HT7044A-1 include Battery checkers, Level selectors, Power failure detectors, Microcomputer reset, Battery memory backup, Non-volatile RAM signal storage protectors.
