SM72240 Overview
The SM72240 microprocessor supervisory circuit monitors the power supplies in microprocessor and digital systems. It provides a reset to the microprocessor during power-up, power-down, brown-out conditions, and manual reset. The SM72240 asserts a reset signal whenever the supply decreases below the factory-programmed reset threshold.
