General Description

The MIC834 is a micropower, precision voltage comparator

with an on-chip voltage reference.

The threshold is adjusted by the choice of two external

resistors. Voltage detection threshold is accurate to 1.5%.

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

ideal for portable applications.

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

5 package.

Typical Application
