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
