AIC1680
Ultra Low Power Voltage Detector
FEATURES
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 hys-
teresis 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.
Ultra-Low Quiescent Current.
1.5V to 10.0V Input Voltage Operation.

Three Output Types: N-ch, P-ch and CMOS.
Space Saving Packages: TO-92, SOT-89,
SOT-23 and SOT23-5.
