Comparator and Reference with Adj. Hystersis Advance Information
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 independently, allowing for wide hysteresis. Three external resistors determine the threshold
voltages.
Voltage detection thresholds 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-235 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
