Product Summary
The MAX690ACSA is a Microprocessor Supervisory Circuit. It reduces the complexity and number of components required for power-supply monitoring and battery-control functions in microprocessor (μP) systems. The MAX690ACSA significantly improves system reliability and accuracy compared to separate ICs or discrete components. The applications of the MAX690ACSA include: Battery-Powered Computers and Controllers, Intelligent Instruments, Automotive Systems, Critical μP Power Monitoring.
