General Description
The LM3722/LM3723/LM3724 microprocessor supervisory circuits monitor the power supplies in
microprocessor and digital systems. They provide a reset to the microprocessor during power-up, power-
down, brown-out conditions, and manual reset.
The LM3722/LM3723/LM3724 asserts a reset signal whenever the supply decreases below the factory-
programmed reset threshold for at least 100 ms. The reset signal remains asserted for 190 ms after VCC
rises above the threshold.
The LM3722 has an active-low RESET# push-pull output. The LM3723 has an active-high RESET push-pull
output. The LM3724 has an active-low open-drain RESET# output.
Three standard reset voltage options are available, suitable for monitoring 5V, 3.3V, and 2.5V supply
voltages. Additional reset voltages are also available; contact National Semiconductor for details.
With a low supply current of only 6A, the LM3722/LM3723/LM3724 are ideal for use in portable equipment.
The LM3722/LM3723/LM3724 are available in the 5-pin SOT23 package.
