Power Supply Supervisors  
Description  
The CAT853, CAT863, CAT859, and CAT869 are supervisory  
circuits that monitor power supplies in digital systems.  
These devices generate a reset signal, which is asserted while the  
power supply voltage is below a preset threshold level and for at least  
140 ms after the power supply level has risen above that level.  
Industry standard threshold levels are offered to support +3.3 V or  
5.0 V systems.

The CAT859 and CAT869 feature a RESET pushpull output  
(active low) for the two pinout options.  
The CAT853 and CAT863 feature an open drain RESET output  
(active low). Both require a pullup resistor on the RESET output.  
Fast transients on the power supply are ignored and the output is
