MAX801L/M/N, MAX808L/M/N
8-Pin µP Supervisory Circuits with ±1.
5% Reset Accuracy
_______________General Description
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.
