TK610xx
ADVANCED
INFORMATION
FEATURES
■ Very Low Quiescent Current ( 1 µA)
■ No External Components
■ Built In Hysteresis (5% typ.)
■ ±2 % Voltage Detection Accuracy
■ Miniature Package (SOT23-5)
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 %).
VOLTAGE DETECTOR
APPLICATIONS
■ Battery Powered Systems
■ Wireless Telephones
■ Pagers
■ Personal Communications Equipment
■ Personal Digital Assistants
