General Description
The MIC834 is a micropower, precision voltage comparator with an on-chip voltage reference.
The threshold is adjusted by the choice of two external resistors. Voltage detection threshold is accurate to 1.5%.
Supply current is extremely low (1.5µA, typical), making it ideal for portable applications.
The MIC834 is supplied in Micrel’s IttyBitty™ 5-lead SOT-23-5 package.

Features
• Optimized for PDAs, cellular telephones, pagers, and other battery-powered devices
• Input and output can be pulled up to 6V regardless of supply voltage
• High ±1.5% voltage threshold accuracy
• Built in hysteresis for noise suppression
• Extremely low 1.5µA typical supply current
• Immune to brief input transients
• 5-lead SOT-23 package

Applications
• PDAs
• Pagers
• Cordless phones
• Consumer electronics
• Embedded controllers
• Personal electronics
