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.
