S-1009 Series SUPER-LOW CURRENT CONSUMPTION SUPER HIGH-ACCURACY VOLTAGE DETECTOR WITH DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING) www.sii-ic.com SII Semiconductor Corporation, 2009-2012 Rev.5.1 01 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. Features Detection voltage: 0.8 V to 4.6 V (0.1 V step) Detection voltage accuracy: 0.5% (2.4 V V 4.6 V) DET 12 mV (0.8 V V < 2.4 V) DET Current consumption: 270 nA typ. (1.2 V V < 2.3 V) DET Operation voltage range: 0.6 V to 10.0 V (CMOS output product) Hysteresis width: 5% 1% Delay time accuracy: 15% (C = 4.7 nF) D Output form: Nch open-drain output (active) CMOS output (active) Operation temperature range: Ta = 40C to +85C Lead-free (Sn 100%), halogen-free Applications Power monitor and reset for CPU and microcomputer Constant voltage power monitor for TV, DVD recorder and home appliance Power supply monitor for portable device such as notebook PC, digital still camera and mobile phone Packages SOT-23-5 SC-82AB SNT-4A 1 SUPER-LOW CURRENT CONSUMPTION SUPER HIGH-ACCURACY VOLTAGE DETECTOR WITH DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING) S-1009 Series Rev.5.1 01 Block Diagrams 1.
