Description

The MCP111/112 is a voltage-detecting device used to keep a microcontroller in reset until the system voltage stabilizes at the appropriate level for reliable system operation. It also provides protection from brown-out conditions when the system supply voltage drops below the specified threshold level. It offers eight different trip voltages to choose from.
