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 re-
quires 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 config-
ured either active high or active low; the open-drain output stage
is only configured active high.
Supply current is extremely low (1.5
μ
A, typical), making it ideal
for portable applications.
The MIC841/2 is supplied in Micrel’s Teeny 5-lead SC-70
package.
