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
ꢀ
ꢀ
ꢀ
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.
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,
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.
SOT-23 and SOT23-5.

ꢀAPPLICATION INFORMATIONS
The timing diagram of VDD and VOUT is shown in below:
CMOS Type
VDET
VHYS
VDD
The guaranteed minimun operation voltage is 1.5V.
As the supply voltage(VDD) is reduced below 1.5V,
the performance degrades, N-ch or P-ch driving ca-
pacity degrades, and the supply current decreases.
AIC1680 isn’t functioning when VDD down to 0.8V.
