Product Summary

The MAX697CPE is a Microprocessor Supervisory Circuit. Supervisory circuit reduces the complexity and number of components required for power supply monitoring and battery control functions in microprocessor systems. These include μP reset and backup-battery switchover, watchdog timer, CMOS RAM write protection, and power-failure warning. The MAX697CPE significantly improves system reliability and accuracy compared to that obtained with separate ICs or discrete components. The applications of the MAX697CPE include Computers, Controllers, Intelligent Instruments, Automotive Systems, Critical μP Power Monitoring.
