MIC841/842 Comparator with 1.
25% Reference and Adjustable Hysteresis General Description The MIC841 and MIC842 are micro-power, precisionvoltage 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 (...
