S-1002 Series www.sii-ic.com © Seiko Instruments Inc., 2014 VOLTAGE DETECTOR WITH SENSE PIN Rev.1.1_00 The S-1002 Series is a high-accuracy voltage detector developed using CMOS technology. The detection voltage is fixed internally with an accuracy of ±1.0% (−VDET(S) ≥ 2.2 V). It operates with current consumption of 500 nA typ. Apart from the power supply pin, the detection voltage input pin (SENSE pin) is also prepared, so the output is stable even if the SENSE pin falls to 0 V. Two output forms Nch open-drain output and CMOS output are available.  Features • Detection voltage: 1.0 V to 5.0 V (0.1 V step) • Detection voltage accuracy: ±1.0% (2.2 V ≤ −VDET(S) ≤ 5.0 V) ±22 mV (1.0 V ≤ −VDET(S) < 2.2 V) • Current consumption: 500 nA typ. • Operation voltage range: 0.95 V to 10.0 V • Hysteresis width: 5% ± 2% • Output form: Nch open-drain output (Active "L") CMOS output (Active "L") • Operation temperature range: Ta = −40°C to +85°C • 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 • SC-82AB Seiko Instruments Inc. 1 VOLTAGE DETECTOR WITH SENSE PIN S-1002 Series  Block Diagrams 1.
