AIC1680 Ultra Low Power Voltage Detector FEATURES DESCRIPTION The AIC1680 is an accurate, ultra-low power 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 consumption voltage detector IC, fabricated with advanced CMOS process. The AIC1680 consists of a comparator, a voltage reference unit, 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. 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 APPLICATIONS a resistor divider, two output drivers, and a and hysteresis voltage are set internally and are Battery Checker for Battery-Operated Systems. CPU & Logic Circuit Reset. Memory Back-up Circuit. Level Discriminator. Power Failure Detector. 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.
