LM809/LM810  
3-Pin Microprocessor Reset Circuits  
General Description  
Features  
n Precise monitoring of 3V, 3.3V, and 5V supply voltages  
n Superior upgrade to MAX809/810  
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.  
n Fully specified over temperature  
n 140ms min. Power-On Reset pulse width, 240ms typical  
Active-low RESET Output (LM809)  
Active-high RESET Output (LM810)  
n Guaranteed RESET Output valid for VCC1V  
n Low Supply Current, 15µA typ.  
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.  
n Power supply transient immunity  
Seven standard reset voltage options are available, suitable  
for monitoring 5V, 3.3V, and 3V supply voltages.  
Applications  
n Microprocessor Systems  
n 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 SOT23 package and in the 6-Lead LLP  
package.  
n Controllers  
n Intelligent Instruments  
n Portable/Battery-Powered Equipment  
n Automotive
