XC6118 Series ETR02013-005 Voltage Detector with Separated Sense Pin & Delay Capacitor Pin GENERAL DESCRIPTION The XC6118 series is a low power consumption voltage detector with high accuracy detection, manufactured using CMOS process and laser trimming technologies. Since the sense pin is separated from the power supply pin, it allows the IC to monitor the other power supply. The XC6118 can maintain the state of detection even when voltage of the monitored power supply drops to 0V. Moreover, a release delay time can be adjusted by the external capacitor connected to the Cd pin. The V pin is available in both CMOS and N-channel open drain output configurations.
