LM809/LM810 3-Pin Microprocessor Reset Circuits
September 2002
LM809/LM810
3-Pin Microprocessor Reset Circuits
General 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.
The function of the LM809/810 is to monitor the V
CC
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 V
CC
rises
above the threshold. The LM809 has an active-low RESET
output, while the LM810 has an active-high RESET output.
Seven standard reset voltage options are available, suitable
for monitoring 5V, 3.3V, and 3V supply voltages.
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.

Note 1:
Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which the device operates
correctly. Operating ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the Electrical
Characteristics.
Note 2:
The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin.
Note 3:
Production testing done at T
A
= +25˚C, over temperature limits guaranteed by design only.
Note 4:
At elevated temperatures, devices must be derated based on package thermal resistance. The device in the SOT23-3 package must be derated at 4mW/˚C
at ambient temperatures above 70˚C. The device has internal thermal protection.
Note 5:
