Ht7039A-1 Sot-89 3-Pin Tinypower Voltage Detector Transistor

General Description
The HT70XXA-1 series devices area set of three terminal low power voltage detectors implemented in CMOS technology. Each voltage detector in the series detects aparticular fixed voltage ranging from 2.2V to 5V. The voltage detectors consist of ahigh-precision and low power consumption standard voltage source as well as acomparator, 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 voltage.Features
· Low power consumption
· Low temperature coefficient
