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.

♦ Precision Voltage Monitoring, ±1.5% Reset

Accuracy

♦ 200ms Power-OK/Reset Time Delay

♦ RESET Output (MAX808)

RESET and RESET Outputs (MAX801)

♦ Watchdog Timer (MAX801)

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.

♦ On-Board Gating of Chip-Enable Signals (MAX808):

Memory Write-Cycle Completion

3ns CE Gate Propagation Delay

♦ 1µA Standby Current

♦ Power Switching:
