MCP120 Description

Short technical summary and product information.

The MCP120 is a supervisory circuit designed to monitor a single voltage rail. It asserts a reset signal when the monitored voltage drops below the 4.625V threshold and maintains the reset for 150ms after the voltage returns above the threshold. The output is open drain, active low, making it compatible with a variety of logic families.

 

This supervisor operates over a temperature range of -40°C to 85°C, suitable for industrial and commercial environments. The device is offered in a through-hole TO-92-3 package (TO-226-3, TO-92-3 (TO-226AA)), which is easy to solder and integrate into prototypes and low-volume production.

 

The MCP120 is ideal for applications requiring reliable power-on reset and brown-out protection for microcontrollers, DSPs, or other digital systems. Its simple three-pin interface (VDD, GND, RESET) minimizes board space and design complexity.
