Product Summary

The MAX691CPE is a supervisory circuit. It reduces the complexity and number of components required for power supply monitoring and battery control functions in microprocessor systems. The MAX691CPE includes μP reset and backup-battery switchover, watchdog timer, CMOS RAM write protection, and power-failure warning. The MAX691CPE significantly improves system reliability and accuracy compared to that obtainable with separate ICs or discrete components. The applications of the MAX691CPE include: computers, controllers, intelligent instruments, automotive systems, critical μP power monitoring.
