Please contact each Web shop for details such as availability of online samples.


The S-1009 Series is a super high-accuracy voltage detectordeveloped using CMOS process. 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.
