Maxim Integrated MAX703CPA+ Microprocessor Supervisory Circuit

The MAX703CPA+ from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V-powered circuits.

This supervisory circuit ensures that the µP is reset to a known state during power-up, power-down, and brown-out conditions. The MAX703CPA+ features a 4.65V threshold detector for power-fail warning, battery backup switching, and µP reset. The reset output is guaranteed to remain in the logic low state for a minimum of 100ms after VCC has risen above the reset threshold level.

The MAX703CPA+ comes in an 8-pin PDIP package, making it convenient for integration into a wide range of applications. Its temperature range of 0°C to +70°C allows for operation in most standard environments. Ideal for use in computers, controllers, intelligent instruments, and critical µP power monitoring, this supervisory circuit is a vital component for enhancing system reliability and performance.

With its combination of features, the MAX703CPA+ provides a compact, efficient, and robust solution for µP systems requiring dependable monitoring and reset capabilities.
