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 7.7V for a 2% tolerance and from
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.
During operation, the TC54's output (V
