AIC1680-C60CV

AIC1680 Ultra Low Power Voltage Detector 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: TO-92, SOT-89, SOT-23 and SOT23-5. DESCRIPTION The AIC1680 is an accurate, ultra-low power consumption voltage detector IC, fabricated with advanced CMOS process. The AIC1680 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 opendrain, P-ch open-drain, and CMOS. Four types of package, TO-92, SOT-89, SOT-23 and SOT23-5, are available to save board space. APPLICATIONS Battery Checker for Battery-Operated Systems. CPU & Logic Circuit Reset.

As the supply voltage(VDD) is reduced below 1.5V, the performance degrades, N-ch or P-ch driving capacity degrades, and the supply current decreases. AIC1680 isn’t functioning when VDD down to 0.8V.
