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 open-drain, P-ch open-drain, and CMOS. Four types of package, SOT23-3, SOT23-5, SOT89-3 and TO92-3, are available to save board space.
