LM809

具有低電平有效推挽復(fù)位功能、用于監(jiān)控電源的 3 引腳電壓監(jiān)控器(復(fù)位 IC); ? Precision Monitoring of Supply Voltages \n? Available Threshold Options: 2.63 V, 2.93 V, 3.08 V, 4.38 V, 4.63 V\n \n? Superior Upgrade to MAX809 and MAX810\n? Fully Specified Over Temperature\n? 140-ms Minimum Power-On Reset Pulse Width, 240-ms Typical \n? Active-Low RESET Output (LM809)\n? Active-High RESET Output (LM810)\n \n? Ensured RESET Output Valid for VCC ≥ 1 V\n? Low Supply Current, 15-μA Typical\n? Power Supply Transient Immunity;

The LM809 and LM810 microprocessors supervisory circuits can be used to monitor the power supplies in microprocessor and digital systems. They provide a reset to the microprocessor during power-up, power-down and brown-out conditions.The function of the LM809 and LM810 are to monitor the VCC supply voltage, and assert a reset signal whenever this voltage declines below the factory-programmed reset threshold. The reset signal remains asserted for 240 ms after VCC rises above the threshold. The LM809 has an active-low RESET output, while the LM810 has an active-high RESET output.Seven standard reset voltage options are available, suitable for monitoring 5-V, 3.3-V, and 3-V supply voltages.With a low supply current of only 15 μA, the LM809 and LM810 are ideal for use in portable equipment.
