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 (1.5µA, typical), making it ideal for portable applications.

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