Description
The
designed to keep a microcontroller in reset until the
system voltage has reached and stabilized at the
proper level for reliable system operation. These
devices also operate as protection from brown-out
conditions when the system supply voltage drops
below a safe operating level. The MCP111 and
MCP112 are available in eight different trip voltages.
The MCP111 has an open-drain output with an active-
low pin (V
