CAT811, CAT812  
4-Pin Microprocessor  
Power Supply Supervisors  
with Manual Reset  
Description  
The CAT811 and CAT812 are microprocessor supervisory circuits  
that monitor power supplies. The CAT811 and CAT812 are direct  
replacements for the MAX811 and MAX812 in applications operating  
over the industrial temperature range; both have a manual reset input.  
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.

SOT−143  
BI SUFFIX  
CASE 527AF  
The CAT811 features a RESET push−pull output (active LOW) and  
the CAT812 features a RESET push−pull output (active HIGH).  
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.  
The CAT811/812 are fully specified over the industrial temperature  
range (−40°C to 85°C) and are available in a compact 4−pin SOT−143  
package.
