Product Description

General Description

The CY70XXA-1 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 highprecision 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
• Built-in hysteresis characteristic
• High input voltage (up to 15V)
• Output voltage accuracy: tolerance ±1% or ±2%
• TO92, SOT89 ,SOT23 and SOT23-3 package
   

Applications    

• Battery checkers
• Level selectors
• Power failure detectors
• Microcomputer reset
• Battery memory backup
• Non-volatile RAM signal storage protectors
