PMIC (Power Management ICs) are essential to modern electronics because they regulate power to the components of integrated circuits. An increasingly popular type of PMIC is the Supervisors, which can sense the power level of a system and respond accordingly. The ADM708RARZ is a Supervisors PMIC that offers an optimal balance between cost and performance. This article will discuss its application field, working principle and features.

Application Field

The ADM708RARZ is a general-purpose integrated supervisor that offers a high level of protection and flexibility. It is suitable for a wide variety of applications, from consumer electronics and automotive systems to industrial control and data acquisition. Its flexibility makes it a great choice for any project that requires a supervisor.

The ADM708RARZ is designed to be very low power and ultra-stable, providing a robust protection system for your circuit. It provides efficient supervision and reset sequences, as well as an integrated voltage monitor and watchdog timer. The ADM708RARZ is also fully qualified to MIL-STD-1813 and has a wide operating temperature range (-40°C to +85°C), making it ideal for harsh environments.

Working Principle

The ADM708RARZ operates by sensing the power level of a given circuit. When the power level drops below a certain threshold, the supervisor will then send a reset signal to the device. This signal will notify the device to resume operations and reset the IC. The ADM708RARZ is also capable of monitoring the voltage levels at each system node, and will trigger an appropriate reset signal if any of these levels is outside of the expected range.

The integrated watchdog timer of the ADM708RARZ is also very useful for detecting and preventing system crashes. It will periodically check the state of the system and if the system does not respond, it will reset the IC. This ensures that the system will always be stable and running efficiently.

Features

The ADM708RARZ offers a wide range of features that make it an excellent choice for supervisors. For example, it has an internal regulated voltage monitor (VRM) that eliminates the need for an external voltage regulator. It also has a paired trigger input pin and output pin which provide an automatic reset when an alarm is triggered. Finally, the device also features built-in ESD protection, a push-pull reset output and an active-low reset input.

The ADM708RARZ is an excellent choice for a wide variety of applications. It is low power, ultra-stable and offers a robust protection system. Its wide operating temperature range and integrated voltage monitor make it ideal for harsh environments. The integrated watchdog timer provides additional safety and the built-in ESD protection ensures that the system will run reliably.
