ADM690AARMZ: An Overview

The ADM690AARMZ is a power management integrated circuit (PMIC) – supervisors that are primarily used in computing applications and industrial automation. It is a low power, low cost and low profile device that is capable of monitoring, controlling and protecting power systems. The ADM690AARMZ provides a host of features including supply monitoring, overvoltage protection, power on reset, thermal shutdown, frequency synchronization and sequence delay functions.

Features

The key features that distinguish the ADM690AARMZ from other PMIC – supervisors are its supply-monitoring capability, overvoltage protection, power-on reset, thermal shutdown, and frequency synchronization. Supply-monitoring provides the ability to detect when the system voltage is below a certain level and then shut down in order to prevent system damage. This helps protect the system from unexpected power outages and ensures that all devices on the system remain adequately powered. Overvoltage protection prevents damage to the system by sensing whenever the voltage of the system exceeds a predetermined threshold. If the voltage exceeds this threshold, the IC will quickly shut down the system in order to protect it from damage.Power-on reset ensures that all the devices on the system are booted up when the power is switched on. This helps ensure that the system is functioning correctly from the start up and that any potential errors or problems can be prevented in the early stages of operation.Thermal shutdown protects the system from overheating by activating a shutdown mode whenever the temperature of the system exceeds a certain level. This feature helps to prevent damage to the system from excessive heat generated during operation.Finally, frequency synchronization allows the IC to maintain the correct frequency for the system. This helps ensure that all components of the system are running at their optimal performance levels, which can improve overall system performance and reliability.

Applications

The ADM690AARMZ is commonly used in computing applications and industrial automation. It is capable of providing reliable power management in a variety of conditions, including those that require frequent power cycling, such as laboratory experiments or industrial applications. In addition, this IC is well-suited for high-performance computing applications that require low power consumption and high accuracy, such as embedded systems and automotive electronics.

Working Principle

The ADM690AARMZ PMIC – supervisors operates by monitoring the system supply voltage. When the system voltage drops below the preset threshold the IC will shut down the system in order to protect it from damage. The IC also has an internal power-on reset circuit that will reset the system when the power is switched on and ensures that all system components are successfully booted up. The IC also has an overvoltage protection feature, which will shut down the system if the voltage exceeds a predetermined threshold. Additionally, the thermal shutdown feature will activate when the temperature of the system exceeds a certain limit, which helps to prevent damage from overheating. Finally, frequency synchronization ensures that the system is running at the correct frequency, which improves system performance and reliability.

Conclusion

The ADM690AARMZ is an attractive solution for power management in computing applications and industrial automation. It provides reliable performance in a variety of conditions and is available at a low cost. The IC has a host of features including supply monitoring, overvoltage protection, power-on reset, thermal shutdown, and frequency synchronization all of which work together to ensure reliable, efficient and safe power management.
