SNVS052E SEPTEMBER 1999REVISED APRIL 2016  
LM809/LM810 3-Pin Microprocessor Reset Circuits  
1 Features  
3 Description  
The LM809 and LM810 microprocessors 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.  
1
Precision Monitoring of Supply Voltages  
Available Threshold Options:  
2.63 V, 2.93 V, 3.08 V, 4.38 V, 4.63 V  
Superior Upgrade to MAX809 and MAX810  
Fully Specified Over Temperature  
The function of the LM809 and LM810 are 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 240 ms after VCC rises above  
the threshold. The LM809 has an active-low RESET  
output, while the LM810 has an active-high RESET  
output.  
140-ms Minimum Power-On Reset Pulse Width,  
240-ms Typical  
Active-Low RESET Output (LM809)  
Active-High RESET Output (LM810)  
Ensured RESET Output Valid for VCC 1 V  
Low Supply Current, 15-µA Typical  
Power Supply Transient Immunity  
Seven standard reset voltage options are available,  
suitable for monitoring 5-V, 3.3-V, and 3-V supply  
voltages.  
2 Applications  
With a low supply current of only 15 µA, the LM809  
and LM810 are ideal for use in portable equipment.
