GENERAL DESCRIPTION
The TC54 Series are CMOS voltage detectors, suited
especially 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 1.1V to 6.0V,
in 0.1V steps 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 (VOUT) remains in the
logic HIGH state as long as VIN is greater than the
specified threshold voltage (V
DET). When VIN falls below
V
DET, the output is driven to a logic LOW. VOUT remains
LOW until VIN rises above V
DET by an amount VHYST,
whereupon it resets to a logic HIGH.
