SUPER-LOW CURRENT CONSUMPTION SUPER HIGH-ACCURACY
VOLTAGE DETECTOR WITH DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING)
Rev.5.1_00
The S-1009 Series is a super high-accuracy
voltage detector developed using
CMOS technology. The detection
voltage is fixed internally with an accuracy of ±0.5%. It operates with super low current consumption of 270 nA typ. The release signal can be delayed by setting a capacitor externally. Delay time accuracy is ±15%. Two output forms Nch open-drain and
CMOS output are available. Compared with conventional
CMOS voltage detectors, the S-1009 Series is the most suitable for the portable devices due to the super-low current consumption, super high-accuracy and small packages.
