TC54
Voltage Detector
General Description
The TC54 Series are CMOS voltage detectors, suited
especially for battery-powered applications because of
their extremely low 1µA operating current and small
surface-mount packaging. Each part is laser trimmed to
the desired threshold voltage which can be specified
from 1.1V to 6.0V and 7.7V, for a 2% and 1.5V to 6.0V
for a 1% tolerance.
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
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
, whereupon it resets to a logic HIGH.
