The MAX792/MAX820 microprocessor (µP) supervisory  
circuits provide the most functions for power-supply  
and watchdog monitoring in systems without battery  
backup. Built-in features include the following:  
Manual-Reset Input  
200ms Power-OK/Reset Time Delay  
Independent Watchdog Timer—Preset or Adjustable  
On-Board Gating of Chip-Enable Signals  
Memory Write-Cycle Completion  
1) µP reset: Assertion of RESET and RESET outputs dur-  
ing power-up, power-down, and brownout condi-  
tions. RESET is guaranteed valid for VCC down to 1V.  
10ns (max) Chip-Enable Gate Propagation Delay  
Voltage Monitor for Overvoltage Warning  
2) Manual-reset input.  
3) Two-stage power-fail warning: A separate low-line  
comparator compares VCC to a preset threshold  
120mV above the reset threshold; the low-line and  
reset thresholds can be programmed externally.  
±2% Reset and Low-Line Threshold Accuracy  
(MAX820, external programming mode)  
Ord e rin g In fo rm a t io n  
4) Watchdog fault output: Assertion of WDO if the watch-  
dog input is not toggled within a preset timeout  
period.

**These parts offer a choice of five different reset threshold volt-  
ages. Select the letter corresponding to the desired nominal  
reset threshold voltage and insert it into the blank to complete the  
part number.  
The MAX792 and MAX820 are identical, except the  
MAX820 guarantees higher low-line and reset threshold  
accuracy (±2%).
