GENERAL DESCRIPTION
The TC54 Series are CMOS voltage detectors, suited
especially for battery-powered applications because of their
extremely low 1
μ
A operating current and small surface-
mount packaging. Each part is laser trimmed to the desired
threshold voltage which can be specified from 2.1V to 6.0V,
in 0.1V steps.
The device includes a comparator, low-current high-
precision reference, laser-trimmed divider, hysteresis circuit
and output driver. The TC54 is available with either an open-
drain or complementary output stage.
In operation, the TC54's output (V
OUT
) remains in the
logic HIGH state as long as V
IN
is greater than the
specified threshold voltage (V
V
LOW until V
IN
rises above V
whereupon it resets to a logic HIGH.
