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.
