Description
19-1086; Rev 1; 11/05 MAX801L/M/N, MAX808L/M/N 8-Pin µP Supervisory Circuits with ±1.5% Reset Accuracy _______________General .
The MAX801/MAX808 microprocessor (µP) supervisory circuits monitor and control the activities of +5V µPs by providing backup-battery switchover, low-l.
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. ________________________Applicatio
