GENERAL DESCRIPTION
The TC51 is a very low power, open drain output, CMOS
voltage detector with built-in delay. It is particularly well-
suited for battery powered applications because of its ex-
tremely low 1
µA
operating current and small surface-mount
packaging. Each part is laser-trimmed to the desired thresh-
old voltage, which can be specified from 1.6V to 6.0V in 0.1V
steps. The standard built-in output delay is 50 msec – 200
msec.
The device includes a comparator, low-current high-
precision reference, laser-programmed voltage divider, hys-
teresis circuit, and output driver with digital delay timer.
In operation, the TC51’s output (V
OUT
) remains in the
logic HIGH state as long as V
IN
is greater than the
specified threshold voltage (V
DET
). When V
IN
falls below
V
DET
, the output is immediately driven to a logic LOW.
V
OUT
remains LOW until V
IN
rises above V
DET
by an
amount V
HYST
, whereupon it returns to a logic HIGH after
expiration of the built-in delay time.
