Comparator and Reference with Adj. Hystersis

Advance Information

General Description

Features

The MIC833 is a micropower precision dual voltage com-

parator with an on-chip reference and latch.

• 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- 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%.

• High ±1% voltage threshold accuracy

• Extremely low 1µA typical supply current

• Immune to brief input transients

• 5-lead SOT-23 package

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.

Applications

• PDAs

• Pagers

• Cordless phones

• Consumer electronics

• Embedded controllers

• Personal electronics
