The LM809M3-2.93/NOPB is a 3-pin Microprocessor Supervisory Circuit with active-low RESET output. The supervisory circuit can be used to monitor the power supplies in microprocessor and digital systems. It provides a reset to the microprocessor during power-up, power-down and brownout 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.

• Power supply transient immunity
• Fully specified over-temperature
• Ensured RESET output valid for VCC >= 1V
• Superior upgrade to MAX809 and MAX810
• 140ms Minimum power-ON reset pulse width
• 15µA Typical low supply current
• Green product and no Sb/Br
