3-Pin Microprocessor  
Power Supply Supervisors  
Description  
The CAT803, CAT809, and CAT810 are supervisory circuits that  
monitor power supplies in digital systems. The CAT803, CAT809, and  
CAT810 are direct replacements for the MAX803, MAX809 and  
MAX810 in applications operating over the industrial temperature range.  
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. The  
underlying floating gate technology, Analog EEPROM used by  
ON Semiconductor, makes it possible to offer any custom reset  
threshold value. Seven industry standard threshold levels are offered  
to support +5.0 V, +3.3 V, +3.0 V and +2.5 V systems.

The CAT803 has an opendrain RESET output (active LOW). The  
CAT803 requires a pullup resistor on the reset output.  
The CAT809 features a pushpull RESET output (active LOW) and  
the CAT810 features a pushpull RESET output (active HIGH).  
Fast transients on the power supply are ignored and the output is

The CAT803, CAT809, and CAT810 are available in both the  
compact 3pin SOT23 and SC70 packages.
