Flexible Detection Voltage Setting
0.1V Step in the Range of 1.6V to 6.0V
High Detection Voltage Accuracy at
±2.5%.
Built-In Detection Voltage Hysteresis.

SOT-23 and SOT23-5.
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 hyste-
resis 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.
APPLICATIONS
Battery Checker for Battery-Operated Systems.
CPU & Logic Circuit Reset.
Memory Back-up Circuit.
Level Discriminator.
Power Failure Detector.
