DESCRIPTION
The AIC1680 is an accurate, ultra-low power
consumption voltage detector IC, fabricated with
advanced CMOS process. The AIC1680 con-
sists 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, TO-92, SOT-89, SOT-23 and SOT-
23-5, are available to save board space.
