S-1003 Series www.sii-ic.com © Seiko Instruments Inc., 2013 MANUAL RESET BUILT-IN DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING) HIGH-ACCURACY VOLTAGE DETECTOR Rev.1.0_00 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% (−VDET ≥ 2.2 V). It operates with current consumption of 500 nA typ. 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: • Detection voltage accuracy: • Current consumption: • Operation voltage range: • Hysteresis width: • Manual reset function: • Delay time accuracy: • Output form: • Operation temperature range: • Lead-free (Sn 100%), halogen-free 1.2 V to 5.0 V (0.1 V step) ±1.0% (2.2 V ≤ −VDET ≤ 5.0 V) ±22 mV (1.2 V ≤ −VDET < 2.2 V) 500 nA typ. 0.95 V to 10.0 V 5% ± 2% MR pin logic active "L", active "H" ±15% (CD = 4.7 nF) Nch open-drain output (Active "L") CMOS output (Active "L") Ta = −40°C to +85°C „ 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 Seiko Instruments Inc. 1 MANUAL RESET BUILT-IN DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING) HIGH-ACCURACY VOLTAGE DETECTOR S-1003 Series Rev.1.0_00 „ Block Diagrams 1.
