Features - - - Low power consumption Low temperature coefficient Built-in high-stability reference source - - Built-in hysteresis characteristic TO-92 & SOT-89 package Applications - - - Battery checkers Level selectors Power failure detectors - - - Microputer reset Battery memory backup Non-volatile RAM signal storage protectors 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 2.4V to 7V. The voltage detectors consist of a high-precision and low power consumption standard voltage source, a parator, 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 ponents to detect user specified threshold voltages (NMOS open drain type only).
