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
IN
is greater than the
specified threshold voltage (V
DET
). When V
IN
falls below
V
DET
, the output is driven to a logic LOW. V
OUT
remains
LOW until V
IN
rises above V
DET
by an amount V
HYST
,
whereupon it resets to a logic HIGH.

How to display the generated waveform on 12864?
I'm planning to make an oscilloscope recently, but I can't think of a good way to display the waveform on 12864. Has anyone done it before? I hope you can give me some advice. Thank you~~~~...

Digital control challenges traditional power supply design concepts
One of the fundamental decisions required at the outset of a power supply design is whether to use voltage mode control (VMC) or current mode control (CMC). For any design, the trade-off is between th...
