Description

General part information

MCP120 Series

The MCP120 is a voltage supervisory device designed to keep a microcontroller in reset until the system voltage has reached the proper level and stabilized. It also operates as protection from brown-out conditions when the supply voltage drops below a safe operating level. MCP120 features an open drain output, and active low reset and is available in a choice of seven different trip voltages. It operates over the extended industrial temperature range (-40°C/+85°C). MCP120 is available in a TO-92, SOT23-3, and SN packages.
