Product Summary

The MAX793SCSE+ is a 3.0V/3.3V Adjustable Microprocessor Supervisory Circuit. It monitors and controls the activities of +3.0V/+3.3V μPs by providing backup-battery switchover, among other features such as low-line indication, μP reset, write protection for CMOS RAM, and a watchdog. The backup-battery voltage of the MAX793SCSE+ can exceed VCC, permitting the use of 3.6V lithium batteries in systems using 3.0V to 3.3V for VCC. The applications of the MAX793SCSE+ include: Battery-Powered Computers and Controllers, Embedded Controllers, Intelligent Controllers, Critical μP Power Monitoring, Portable Equipment.
