The LM809M3-3.08 is a 3-pin microprocessor Reset Circuit can be used to monitor the power supplies in microprocessor and digital systems. This reset circuit provides a reset to the microprocessor during power-up, power-down and brown-out conditions. The function of the LM809 is 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 240ms after VCC rises above the threshold. This circuit has an active-low RESET output. The standard reset voltage option is available and has 3.08V threshold voltage.
• Fully specified over-temperature
• Active-low RESET output
• Ensured RESET output valid for VCC>,=1V
• 15µA Typical low supply current
• Power supply transient immunity
