XC6119 Series ETR02016-004 Voltage Detector with Delay Time Adjustable GENERAL DESCRIPTION The XC6119 series is a highly precise, low power consumption voltage detector, manufactured using CMOS and laser trimming technologies. The device includes the built-in delay circuit. A release delay time can be set freely by connecting an external delay capacitor to the Cd pin. The device using an ultra small package (USPN-4) is suited for high density mounting applications. Both CMOS and N-channel open drain output configurations are available.
