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.

Features
• 1.5V to 5.5V operating range
• 1.5μA typical supply current
• ±1.25% voltage threshold accuracy
• 10nA max input leakage current over temperature
• 10µs propagation delay
• Externally adjustable hysteresis (MIC841)
• Internal 20mV hysteresis (MIC842)
• Output options
    - Push-pull, active high
    - Push-pull, active low
    - Open drain, active low
• Open drain output can be pulled to 6V regardless of VDD
• Immune to brief input transients
• Teeny™ 5-pin SC-70 package

Applications
• Smart phones
• PDAs
• Precision battery monitoring
• Battery chargers
