Advance Information

General Description

Features

The MIC834 is a micropower, precision voltage comparator

with an on-chip voltage reference.

• Optimized for PDAs, cellular telephones, pagers,

and other battery-powered devices

• Input and output can be pulled up to 6V

regardless of supply voltage

The threshold is adjusted by the choice of two external

resistors. Voltage detection threshold is accurate to 1%.

• High ±1% voltage threshold accuracy

• Built in hysteresis for noise suppression

• Extremely low 1.5µA typical supply current

• Immune to brief input transients

Supply current is extremely low (1.5µA, typical), making it

ideal for portable applications.

The MIC834 is supplied in Micrel’s IttyBitty™ 5-lead SOT-23-

5 package.

• 5-lead SOT-23 package

Applications

• PDAs

• Pagers

• Cordless phones
