ULTRA-SMALL PACKAGE HIGH-PRECISION VOLTAGE DETECTOR WITH DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING)
S-809xxC Series
The S-809xxC Series is a high-precision voltage detector developed using CMOS process. The detection voltage is fixed internally with an accuracy of ±2.0 %. A time delayed reset can be accomplished with the addition of an external capacitor. Two output forms, Nch open-drain and CMOS output, are available.
Features
• Ultra-low current consumption • • • • • • 1.0 μA typ. (Detection voltage ≤ 1.4 V, at VDD=2.0 V) 1.1 μA typ. (Detection voltage ≥ 1.5 V, at VDD=3.5 V) High-precision detection voltage ±2.0 % Operating voltage range 0.7 V to 10.0 V Hysteresis characteristics 5 % typ. Detection voltage 1.3 V to 6.0 V (0.1 V step) Output forms Nch open-drain output (Active Low) CMOS output (Active Low) Lead-free products
Applications
• Power supply monitor for portable equipment such as notebook PCs, digital still cameras, PDAs and cellular phones • Constant voltage power monitor for cameras, video equipment and communication equipment • Power monitor and reset for CPUs and microcomputers
