Functional Features

  • Monitors the supply voltage and generates a reset signal when it falls below a certain threshold.
  • Provides a precision monitoring solution for microprocessors and other digital systems.
  • Offers a low power consumption design, suitable for battery-powered applications.
  • Includes a reset timeout feature to ensure proper system initialization.

Advantages

  • Wide supply voltage range allows for versatile use in various electronic systems.
  • Precision monitoring ensures reliable operation of microprocessors and digital circuits.
  • Low quiescent current minimizes power consumption, extending battery life.
