FEATURES  
DESCRIPTION  
The LM809/810 microprocessor supervisory circuits  
can be used to monitor the power supplies in  
microprocessor and digital systems. They provide a  
reset to the microprocessor during power-up, power-  
down and brown-out conditions.

Precise Monitoring of 3V, 3.3V, and 5V Supply  
Voltages  
Superior Upgrade to MAX809/810  
Fully Specified Over Temperature  
140ms Min. Power-On Reset Pulse Width,  
240ms Typical  
The function of the LM809/810 is to monitor the VCC  
supply voltage, and assert a reset signal whenever  
this voltage declines below the factory-programmed  
reset threshold. The reset signal remains asserted for  
240ms after VCC rises above the threshold. The  
LM809 has an active-low RESET output, while the  
LM810 has an active-high RESET output.  
Active-Low RESET Output (LM809)  
Active-High RESET Output (LM810)  
Ensured RESET Output Valid for VCC1V  
Low Supply Current, 15µA Typ  
Power Supply Transient Immunity  
Seven standard reset voltage options are available,  
suitable for monitoring 5V, 3.3V, and 3V supply  
voltages.  
APPLICATIONS  
Microprocessor Systems  
Computers  
With  
a low supply current of only 15µA, the  
LM809/810 are ideal for use in portable equipment.  
The LM809/LM810 are available in the 3-pin SOT-23  
package and in the 6-Lead SON package.
