  • Low quiescent current consumption
  • Wide operating voltage range

Advantages and Disadvantages

Advantages: - Reliable voltage monitoring and reset generation - Flexible threshold voltage options - Manual reset capability for immediate system reset - Low power consumption - Wide operating temperature range

Disadvantages: - Limited reset timeout period options - Only available in SOIC-8 package

Working Principles

The ADM705AR is designed to monitor the power supply voltage of a system. It compares the supply voltage with a specified threshold voltage. When the supply voltage falls below the threshold, the ADM705AR generates a reset signal. This reset signal can be used to initiate a system reset or to trigger other actions.

The reset output remains low until the supply voltage rises above the threshold and the reset timeout period elapses. The reset timeout period can be selected based on the specific requirements of the application.

Detailed Application Field Plans

The ADM705AR is commonly used in various electronic systems where reliable voltage monitoring and reset generation are critical. Some typical application fields include:

  1. Microcontrollers and microprocessors
  2. Embedded systems
  3. Industrial control systems
  4. Communication equipment
  5. Power management systems
  6. Automotive electronics
