General Description

The TC54 series are CMOS voltage detectors that are

especially well suited for battery-powered applications

because of their extremely low 1 µA operating current

and small surface-mount packaging. Each part is laser-

trimmed to the desired threshold voltage, which can be

specified from 1.4V to 6.0V with a 2% tolerance.

The TC54 is available with either an open-drain or com-

plementary output stage. During operation, the TC54's

output (V

resets to a logic-high.
