Microprocessor Supervisory Circuits  
General Description  
____________________________Features  
ꢀ 200ms Power-OK/Reset Timeout Period  
The MAX691A/MAX693A/MAX800L/MAX800M micro-  
processor (µP) supervisory circuits are pin-compatible  
upgrades to the MAX691, MAX693, and MAX695. They  
improve performance with 30µA supply current, 200ms  
typ reset active delay on power-up, and 6ns chip-  
enable propagation delay. Features include write pro-  
tection of CMOS RAM or EEPROM, separate watchdog  
outputs, backup-battery switchover, and a RESET out-  
put that is valid with VCC down to 1V. The MAX691A/  
MAX800L have a 4.65V typical reset-threshold voltage,  
and the MAX693A/MAX800Ms’ reset threshold is 4.4V  
typical. The MAX800L/MAX800M guarantee power-fail  
accuracies to 2ꢀ.  
ꢀ 1µA Standby Current, 30µA Operating Current  
ꢀ On-Board Gating of Chip-Enable Signals,  
10ns max Delay  
ꢀ MaxCap™ or SuperCap™ Compatible  
ꢀ Guaranteed RESET Assertion to VCC = +1V  
ꢀ Voltage Monitor for Power-Fail or Low-Battery  
Warning  
ꢀ Power-Fail Accuracy Guaranteed to 2ꢀ  
(MAX800L/M)  
ꢀ Available in 16-Pin Narrow SO, Plastic  
DIP, and TSSOP Packages
