◆CMOS ◆Highly Accurate : +2% ◆Ultra Low Power Consumption : 0.8µA(TYP.) (VIN = 2.0V) ◆Separated Sense Pin ◆Built-In Delay Circuit, Delay Pin Available ■APPLICATIONS ●Microprocessor reset circuitry ●Charge voltage monitors ●Memory battery back-up switch circuits ●Power failure detection circuits ■GENERAL DESCRIPTION The XC6108 series is highly precise, low power consumption voltage detector, manufactured using CMOS and laser trimming technologies. Since the sense pin is separated from power supply, it allows the IC to monitor added power supply. Using the IC with the sense pin separated from power supply enables output to maintain the state of detection even when voltage of the monitored power supply drops to 0V. Moreover, with the built-in delay circuit, connecting the delay capacitance pin to the capacitor enables the IC to provide an arbitrary release delay time. Both CMOS and N-channel open drain output configurations are available. ■FEATURES Highly Accurate :+2% (Setting Detect Voltage≧1.5V) :+30mV (Setting Detect Voltage＜1.5V) Ultra Low Power Consumption : 0.8 µA (TYP.)
