EC9508C/EC9509C-BUILT-IN DELAY Voltage Detector

General description

The EC9509C / 08C 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.
