TC54

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 and 7.7V, 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 V

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.

Temp. Range

-40°C to +85°C
