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 a

particular fixed voltage ranging from 2.2V to 5V. 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.

Features

· Low power consumption

· Low temperature coefficient

· High input voltage range (up to 24V)

· Output voltage accuracy: tolerance ± 3%

· Built-in hysteresis characteristic

· TO-92, SOT-89 and SOT-25 package

Applications

· Battery checkers

· Level selectors

· Power failure detectors

· Microcomputer reset

· Battery memory backup

· Non-volatile RAM signal storage protectors
