XC6109
Series
Voltage Detector with External Delay Type Capacitor
ETR0206_006
■GENERAL
DESCRIPTION
The XC6109 series is highly precise, low power consumption voltage detector, manufactured using CMOS and laser trimming
technologies.
With the built-in delay circuit, connecting the delay capacitance pin to the capacitor enables the IC to provide an arbitrary
release delay time.
Using a small package (SSOT-24), the series is suited for high density mounting.
Both CMOS and N-channel open drain output configurations are available.
■APPLICATIONS
●Microprocessor
reset circuitry
●Charge
voltage monitors
●Memory
battery back-up switch circuits
●Power
