  3. RESET: This pin outputs a reset signal when the monitored voltage drops below the threshold.

Functional Features

  • Voltage Monitoring: ADM809MARTZ-REEL continuously monitors the supply voltage.
  • Reset Generation: When the voltage falls below the specified threshold, the RESET pin becomes active, generating a reset signal.
  • Precision: The IC provides accurate voltage monitoring and precise reset generation.
  • Power-On Reset Delay: It ensures that the reset signal remains active for a specific duration after power is applied or restored.

Advantages and Disadvantages

Advantages

  • Reliable voltage monitoring and reset functionality.
  • Low power consumption, suitable for battery-powered applications.
  • Wide operating voltage range allows compatibility with various systems.
  • Compact package size enables space-saving designs.

Disadvantages
