General Description

The MIC833 is a micropower precision dual voltage comparator with an on-chip reference and latch.

High- and low-voltage thresholds are adjusted indepen dently, allowing for wide hysteresis. Three external resistors determine the threshold voltages. Voltage detection thresh olds are accurate to 1.5.

Features

• Optimized for PDAs, cellular telephones, pagers, and other battery-powered devices

• Inputs and output can pulled up to 6V regardless of supply voltage

• Independently adjustable high- and low-voltage thresholds

• High ±1.5 voltage threshold accuracy

• Extremely low 1µA typical supply current

• Immune to brief input transients

• 5-lead SOT-23 package

Applications

• PDAs

• Pagers

• Cordless phones

• Consumer electronics

• Embedded controllers

• Personal electronics
