National Semiconductor LM3724
The LM3724 has an active-low open-drain RESET output. With a low supply current of only 6µA, the LM3722/LM3723/ LM3724 are ideal for use in portable equipment. The LM3722/ LM3723/LM3724 are available in the 5-pin SOT23 package.| Part No. | LM3724 |

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. Reset will be asserted for at least 100ms even after VCC rises above the reset threshold. The LM3722 has an active-low RESET push-pull output. The LM3723 has an active-high RESET push-pull 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.FEATURES
