Advance Information
General Description
The MIC833 is a micropower precision dual voltage com-
parator 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%.
Supply current is extremely low (1µA, typical), making it ideal
for portable applications.
The MIC833 is supplied in Micrel’s IttyBitty™ 5-lead SOT-23-
5 package.
See the MIC2778 for applications requiring an output delay.
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% 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
