PMIC (Power Management Integrated Circuit) Supervisors are used to monitor and regulate voltage in an electrical system. ADM697ARZ-REEL is one such PMIC Supervisor and is used in many applications ranging from automotive to consumer electronics. In this article, we will explore the application fields, features, and the working principle of this versatile Power Management Integrated Circuit.

Application Fields

ADM697ARZ-REEL is applicable to automotive, consumer, and industrial applications. Most commonly, it is used in automotive audio systems and air conditioning units as a voltage supervisor. It can also be found in industrial control systems and consumer appliances. For example, it can be used to regulate the voltage in battery powered appliances, or as a supervisor in lithium-ion batteries.

In automotive applications, the ADM697ARZ-REEL can be used to provide voltage feedback safety to any number of components in the system. It ensures the system voltage is within predefined limits and protects against overvoltage, undervoltage, and reverse polarity conditions. It can also be used as a power-on reset device in some controllers.

In consumer applications, the ADM697ARZ-REEL is used to monitor system and battery voltages. It can be used as a voltage supervisor for consumer electronics, battery-powered devices, and appliances. It can also be used as a power-on reset device in controllers.

Features

The ADM697ARZ-REEL has an operating temperature range of -40 to 125 degrees Celsius, making it suitable for a wide range of applications. It has a typical quiescent current of 40 μA at 3.3 V, making it suitable for low power applications. It also has an adjustable threshold voltage to allow for a wide range of thresholds, making it easy to tailor it to the application\'s needs. It also has overvoltage and reverse polarity protection. Overall, the ADM697ARZ-REEL is a versatile and robust supervisor suitable for a wide array of applications.

Working Principle

The ADM697ARZ-REEL works by monitoring the input voltage and providing an output signal if the system voltage falls below a predetermined threshold. If the voltage is too low, the supervisor will activate an alarm, which can be used to shut down the system or prevent a dangerous condition from occurring. If the voltage is too high, the supervisor will also activate an alarm to indicate that the system protection circuitry must be activated. This signal can also be used to turn off any external loads that may be connected to the system.

The ADM697ARZ-REEL also has overvoltage protection, which triggers when the input voltage exceeds the adjustable threshold voltage. In this case, the supervisor will activate an alarm and shut down the system, preventing further damage. Reverse polarity protection is also included, which will prevent the supervisor from activating if the system is connected in reverse polarity.

Overall, the ADM697ARZ-REEL is an excellent supervisor for a wide range of applications. It provides excellent overvoltage protection and reverse polarity protection, making it suitable for use in a variety of environments. Its adjustable threshold voltage and wide operating temperature range make it easy to tailor to different applications. Finally, its low quiescent current makes it suitable for low power applications.
