HT70xxA-3
TinyPowerTM Voltage Detector
General Description
The HT70xxA-3 series devices area 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
8.2V. 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.
