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.
