S-1003 Series MANUAL RESET BUILT-IN DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING) www.ablic.com HIGH-ACCURACY VOLTAGE DETECTOR www.ablicinc.com ABLIC Inc., 2013 Rev.1.0 03 The S-1003 Series is a high-accuracy voltage detector developed using CMOS technology. The detection voltage is fixed internally with an accuracy of 1.0% ( V 2.2 V). It operates with current consumption of 500 nA typ. DET The release signal can be delayed by setting a capacitor externally. Delay time accuracy is 15%. Moreover, since the S-1003 Series includes the manual reset function, the reset signal can be also output forcibly. Two output forms Nch open-drain output and CMOS output are available. Features Detection voltage: 1.2 V to 5.0 V (0.1 V step) Detection voltage accuracy: 1.0% (2.2 V V 5.0 V) DET 22 mV (1.2 V V 2.2 V) DET Current consumption: 500 nA typ. Operation voltage range: 0.95 V to 10.0 V Hysteresis width: 5% 2% Manual reset function: MR pin logic active, active 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 supply monitor for microcomputer and reset for CPU Constant voltage power supply monitor for TV, Blu-ray recorder and home appliance Power supply monitor for portable devices such as notebook PC, digital still camera and mobile phone Packages SOT-23-5 SNT-6A 1 MANUAL RESET BUILT-IN DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING) HIGH-ACCURACY VOLTAGE DETECTOR S-1003 Series Rev.1.0 03 Block Diagrams 1.
