ADM8690ARN-REEL

Introduction to PMIC Supervisors

Power management integrated circuits (PMIC) are electrical circuits designed to provide power and functional control over electronic circuits by monitoring and controlling their power states. PMICs are essential to the operation of most of today\'s electronic devices, and are used in applications ranging from low power personal electronics to large-scale industrial systems. One type of PMIC is the supervisor, which provides an extra layer of monitoring for power by tracking and controlling the voltage and current in a system. This article will explore the application field and working principle of ADM8690ARN-REEL, a supervisor from Analog Devices.

Working Principle of ADM8690ARN-REEL

The ADM8690ARN-REEL is a supervisor designed to provide protection and additional functionality to a power system. It functions by monitoring, controlling, and adjusting the power supplied to the system. The supervisor works by monitoring the voltage and current supplied to the system and comparing it to a predetermined limit. If the current or voltage exceeds or falls below the limit, the supervisor will either shut off the supply or adjust it to the pre-set voltage and current level. The supervisor also features an internal chip that is triggered when the voltage and current levels reach a certain level. The chip will then adjust the supply accordingly until the levels are back within their pre-set range. This ensures a stable and reliable supply of power for the system. In addition, the supervisor also features a watchdog timer and adjustable output voltage. The watchdog timer keeps track of the supply’s operation, and will shut off the supply if it detects any abnormalities in the system. The adjustable output voltage is used to adjust the voltage of the supply to suit the needs of the system.

Conclusion

The ADM8690ARN-REEL supervisor is an essential component of any power system. It is designed to provide protection and additional functionality by monitoring and controlling the voltage and current supplied to the system. It is available in various packages and is compatible with a wide range of temperature ranges, making it suitable for use in a variety of applications. The supervisor also features an internal chip that adjusts the supply as needed, as well as a watchdog timer and adjustable output voltage.
