Revision 4.1
General Description
The MIC841 and MIC842 are micropower, precision
voltage comparators with an on-chip voltage reference.
Both
devices
are
intended
for
voltage
monitoring
applications. External resistors are used to set the voltage
monitor
threshold.
When
the
threshold
is
crossed,
the outputs switch polarity.
The
MIC842
incorporates
a
voltage
reference
and
comparator with fixed internal hysteresis; two external
resistors are used to set the switching threshold voltage.
The MIC841
provides
a similar function
with
user
adjustable hysteresis; this part requires three external
resistors
to
set
the
upper
and
lower
thresholds
(the difference between the threshold voltages being the
hysteresis voltage).
Both the MIC841 and MIC842 are available with push-pull
or open-drain output stage. The push-pull output stage is
configured either active high or active low; the open-drain
output stage is only configured active low.
Supply current is extremel
y low (1.5μA, typical), making it
ideal for portable applications.
The MIC841/2 is supplied in Micrel’s Teeny 5-pin
SC-70, 6-pin 1.6mm × 1.6mm Thin DFN (MIC841), and 4-
pin 1.2mm × 1.6mm Thin DFN (MIC842) packages.
Datasheets and support documentation are available on
Micrel’s web site at: www.micrel.com.
