Micrel
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
