MIC833
Comparator and Reference with Adjustable
Hystersis General Description Features 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 1.5%. Supply current is
extremely low (1ВµA, typical), making it ideal for portable
applications.
The MIC833 is supplied in Micrel’s 5-lead SOT-23
package. See the MIC2778 for applications requiring an
output delay.
Data sheets and support documentation can be found on
Micrel’s web site at: www.micrel.com. 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 В±1.5% voltage threshold accuracy Extremely low 1ВµA typical supply current Immune to brief input transients 5-lead SOT-23 package Applications PDAs
