EC9518C/19C – VOLTAGE DETECTOR

General description

The EC9518C / 9519C Series is a high-precision voltage detector developed using CMOS process. The detection voltage is fixed internally with an accuracy of ±2.0 %. A time delayed reset can be accomplished with the addition of an external capacitor. Two output forms, N-channel open-drain and CMOS output, are available.
