3-Pin Microprocessor Power Supply Supervisors  
DESCRIPTION  
FEATURES  
The CAT853, CAT863, CAT859, and CAT869 are  
supervisory circuits that monitor power supplies in  
digital systems.  
„ Precision monitoring of +3.3 V (-5%, -10%), 5 V  
(-10% Power Supplies)  
„ Active low reset output  
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.  
„ Reset valid down to VCC = 1.0 V  
„ 6 µA power supply current  
„ Power supply transient immunity  
„ Industrial temperature range: -40ºC to +85ºC  
„ RoHS-compliant SOT-23 package  
¯¯¯¯¯¯  
The CAT859 and CAT869 feature a RESET push-pull  
output (active low) for the two pinout options.  
APPLICATIONS  
„ Computers  
The CAT853 and CAT863 feature an open drain  
¯¯¯¯¯¯  
RESET output (active low). Both require a pull-up  
„ Servers  
resistor on the RESET output.  
„ Laptops  
Fast transients on the power supply are ignored and  
the output is guaranteed to be in the correct state at  
VCC levels as low as 1.0 V.  
„ Cable modems  
„ Wireless communications  
„ Embedded control systems  
„ White goods  
„ Power meters
