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.
