Applications
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 output
(V OUT ) remains in the logic-high state as long as V IN is

greater than the specified threshold voltage (V DET –).
When V IN falls below V DET –, the output is driven to a
logic-low. V OUT remains low until V IN rises above
V DET – by an amount V HYST , when it resets to a logic-
high state.
