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.
