GENERAL DESCRIPTION

The TC54 Series are CMOS voltage detectors, suited

especially for battery-powered applications because of their

extremely low 1µA 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 (V

OUT

) remains in the

logic HIGH state as long as V

is greater than the

–

specified threshold voltage (V

DET

). When V

falls below

–

DET

, the output is driven to a logic LOW. V

OUT

remains

–

LOW until V

rises above V

DET

by an amount V

HYST

whereupon it resets to a logic HIGH.
