3-Pin Microprocessor Reset Circuits  
General Description  
Benefits and Features  
● Precision Monitoring of +2.5V, +3V, +3.3V, and  
+5V Power-Supply Voltages  
The MAX803/MAX809/MAX810 are microprocessor (μP)  
supervisory circuits used to monitor the power supplies  
in μP and digital systems. They provide excellent circuit  
reliability and low cost by eliminating external components  
and adjustments when used with +5V, +3.3V, +3.0V, or  
+2.5V powered circuits.  
● Fully Specified Over Temperature  
● Available in Three Output Configurations  
• Open-Drain RESET Output (MAX803)  
• Push-Pull RESET Output (MAX809)  
• Push-Pull RESET Output (MAX810)  
● 140ms (min) Power-On-Reset Pulse Width  
● 12μA Supply Current  
Guaranteed Reset Valid to V  
● Power Supply Transient Immunity  
● No External Components  
These circuits perform a single function: they assert a  
reset signal whenever the V  
below a preset threshold, keeping it asserted for at least  
supply voltage declines

= +1V

140ms after V has risen above the reset threshold.

Reset thresholds suitable for operation with a variety of  
supply voltages are available.  
● 3-Pin SC70 and SOT23 Packages  
● AEC-Q100 Qualified. Refer to Ordering Information  
The MAX803 has an open-drain output stage, while the  
MAX809/MAX810 have push-pull outputs. The MAX803’s  
open-drain RESET output requires a pullup resistor that

can be connected to a voltage higher than V . The

MAX803/MAX809 have an active-low RESET output,  
while the MAX810 has an active-high RESET output. The  
reset comparator is designed to ignore fast transients on  
V
, and the outputs are guaranteed to be in the correct

Low supply current makes the MAX803/MAX809/MAX810  
ideal for use in portable equipment. The MAX803 is  
available in a 3-pin SC70 package, and the MAX809/  
MAX810 are available in 3-pin SC70 or SOT23 packages.
