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 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 (VOUT) remains in
the logic-high state as long as VIN is greater than the
specified 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.
