Critical uP and uC Power Monitoring
Portable/Battery-Powered Equipment
Typical Application Circuit
PC611
Description
The
PC611is
a
low-power
microprocessor
(μP)
supervisory
circuit
used
to
monitor
power
supplies
in
microprocessor
and
digital
systems.
Low
supply
current
makes
the
PC611ideal
for
use
in
portable
equipment.
The
device
comes
in
a
4-pin
SOT-143
package.
The
PC611provides
excellent
circuit
reliability
and
low
BOM
cost
by
eliminating
external
components
and
adjustments
when
used
with
5V-powered
or
3V-powered
circuits.
The
PC611also
provides
a
debounced
manual
reset
input.
The
function
of
this
device
is
to
assert
a
reset
if
either
the
power
supply
drops
below
a
designed
———
reset
threshold
level
or
MR
is
forced
low.
The
reset
comparator
is
designed
to
ignore
fast
transients
on
V
CC
.
Reset
thresholds
are
available
for
operation
with
a
variety
of
supply
voltages.
