Description



Description

The MIC841 and MIC842 are micropower, precision voltage comparator with an on-chip voltage reference.

Both devices of MIC841/2 are intended for voltage monitoring applications, external resistors are used to set the voltage monitor threshold and 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 of MIC841/2 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 outputs and active-high or active-low inputs. The active-low part is also available with an open-drain output.

Supply current of MIC841/2 is extremely low (1.5µA, typical), making it ideal for portable applications.

The MIC841/2 is supplied in Micrel's Teeny™ 5-lead SC-70 package.
