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, powerdown, brown-out conditions, and manual reset. The LM3722/LM3723/LM3724 asserts a reset signal whenever the supply decreases below the factoryprogrammed reset threshold. Reset will be asserted for at least 100ms even after VCC rises above the reset threshold.
