Comparator and Reference with Adj. Hystersis
Final 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 1.5%.
Supply current is extremely low (1µA, typical), making it ideal
for portable applications.
The MIC833 is supplied in Micrelâs 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
