The MAX801/MAX808 microprocessor (µP) supervisory circuits monitor and control the activities of +5V µPs by providing backup-battery switchover, low-line indication, and µP reset. Additional features include a watchdog for the MAX801 and CMOS RAM write protection for the MAX808.
The MAX801/MAX808 offer a choice of reset-threshold voltage (denoted by suffix letter): 4.675V (L), 4.575V (N), and 4.425V (M). These devices are available in 8-pin DIP and SO packages.
Applications
- Computers: Desktop, Workstation, Server
- Controllers
- Critical µP Monitoring
