MAX808M - Maxim Integrated Products

MAX808M 8-Pin uP Supervisory Circuits

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 l.
