_______________General Desc ription
The MAX801/MAX808 microprocessor (μP) supervisory
circuits monitor and control the activities of +5V μPs by
providing backup-battery switchover, low-line indica-
tion, and μP reset. Additional features include a watch-
dog 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.
