MCP111/MCP112 Data Sheet
http://www.microchip.com/stellent/images/mchpsiteimages/dwnfolder.gifMCP111/MCP112 Data SheetThe MCP111/112 Series are CMOS voltage detectors are well suited for portable, consumer electrics applications due to the extremely low 1uA operating current and small surface-mount packaging. These devices are designed to hold the microcontroller in reset until the supply voltage reaches a predetermined operating level. These devices also protect against brownout conditions that occur as a result of the supply voltage dropping below a tolerable level.
