SSR1680
Ultra Low Power Voltage Detector
Description:
The SSR1680 is an accurate, ultra-low power consumption voltage detector IC, fabricated with
advanced CMOS process. The SSR1680 consists of a comparator, a voltage reference unit, a resistor
divider, two output drivers, and a hysteresis circuit.
The consumption current is so low that it can often be ignored when compared to the battery self-
discharge current. The values of detection and hysteresis voltage are set internally and are accurately
controlled by trimming techniques. There are three types of output: N-ch open-drain, P-ch open-drain,
and CMOS. SOT-23 is available to save board space.
Features:
• Ultra-Low Quiescent Current.
• 1.5V to 10.0V Input Voltage Operation.
• Flexible Detection Voltage Setting 0.1V Step in the Range of 1.6V to 6.0V
• High Detection Voltage Accuracy at ±2.5%.
• Built-In Detection Voltage Hysteresis.
• Three Output Types: N-ch, P-ch and CMOS.
• Space Saving Packages: SOT-23.
Applications:
• Battery Checker for Battery-Operated Systems.
• CPU & Logic Circuit Reset.
• Memory Back-up Circuit.
• Level Discriminator.
• Power Failure Detector.
Typical application circuit:
• China - Germany - Korea - Singapore - United States •
