General Description

The MCP111/112 are voltage-detecting devices

designed to keep a microcontroller in reset until the

system voltage has stabilized at the appropriate level

for reliable system operation. These devices also

operate as protection from brown-out conditions when

the system supply voltage drops below the specified

threshold voltage level. Eight different trip voltages are

available.
