General Description
The TC54 Series are CMOS voltage detectors that are
especially well suited for battery-powered applications
because of their extremely low 1 A 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 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 (VOUT) remains in the
logic-high state as long as VIN is greater than the spec-
ified threshold voltage (VDET -). When VIN falls below
VDET-, the output is driven to a logic-low. VOUT remains
low until VIN rises above VDET - by an amount VHYST,
whereupon it resets to a logic-high.
