具有手動復位功能的低功耗電壓監(jiān)控器和復位 IC; ? Precise Monitoring of 2.5V, 3.3V, and 5V Supply Voltages\n? Fully Specified Over Temperature \n? Industrial: ?40°C to +85°C\n? Extended: ?40°C to +125°C\n \n? 100 ms Minimum Power-On Reset pulse Width, 190 ms Typical: \n? Active-Low RESET Output (LM3722)\n? Active-High RESET Output (LM3723)\n? Active-Low RESET Open Drain Output (LM3724)\n \n? Guaranteed RESET Output Valid for VCC ≥ 1V \n? Low Supply Current, 6μA Typical\n? Power Supply Transient Immunity\n? Compatible with MAX811/812 Applications;

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. 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 Texas Instruments for details.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 SOT-23 package.
