MIC841/842
Comparator with 1.25% Reference and Adjustable Hysteresis
General Description
The MIC841 and MIC842 are micro-power, 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.
