DESCRIPTION
The TK610xx family of voltage detectors is designed to
provide accurate monitoring of the battery voltage. These
low powered CMOS devices require no external
components and are available in 0.1 V steps from 2.0 V to
5.0 V.
When the input voltage reaches the detection voltage, the
output goes low. This detection voltage has a
±
2 %
accuracy and is set at the factory. When the input voltage
goes high, the output will stay low until the voltage reaches
the detection voltage plus hysteresis (+3 to +7 %).
The TK610xx is available in a miniature SOT23-5 surface
mount package.
