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
A 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 (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 immediately driven to a logic LOW.
VOUT remains LOW until VIN rises above V
–
DET by an
amount VHYST, whereupon it returns to a logic HIGH after
expiration of the built-in delay time.
