Overview

LM3722/LM3723/LM3724 5-Pin Microprocessor Reset Circuits June 2001 LM3722/LM3723/LM3724 5-Pin Microprocessor Reset Circuits 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 ...
