TX70XXH General Description:
The TX70XXH 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
