XC6120 Series
ETR0209-009
Highly Accurate, Ultra Small, Low Power Consumption Voltage Detector
■GENERAL DESCRIPTION
The XC6120 series are highly precise, low power consumption voltage detectors, manufactured using CMOS and laser
trimming technologies. With low power consumption and high accuracy, the series is suitable for precision mobile equipment.
The XC6120 in ultra small packages are ideally suited for high-density mounting. The XC6120 is available in both CMOS and
N-channel open drain output configurations.
■APPLICATIONS
●Microprocessor reset circuitry
●Memory battery back-up circuits
●Power-on reset circuits
●Power failure detection
●System battery life and charge voltage monitors
