Description
The
MCP111/112
are
voltage-detecting
devices
designed to keep a microcontroller in reset until the
system voltage has reached, and 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 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 (VOUT). This device will assert VOUT when the
voltage on the VDD pin is below the trip-point voltage.
The MCP112 has a push-pull output and will assert an
active-low signal (VOUT pin) when the voltage on the
VDD pin is below the trip-point voltage.
During operation, the output (VOUT) remains at a logic-
high as long as VDD is greater than the specified
threshold voltage. When VDD falls below the voltage
trip point, VOUT is driven low.
