Introduction to PMIC - Supervisors

Power Management Integrated Circuits (PMIC) – Supervisors are an integral part of any given system. Supervisors serve as the bridge between the chip and other components, allowing it to interact more efficiently with external components and enabling it to perform specific tasks more effectively. In this article, we are going to take a further look at one particular type of PMIC - Supervisors, the ADM1068ASTZ, and how it is used in different application fields, as well as its working principle.

Application Fields of the ADM1068ASTZ

The ADM1068ASTZ is a type of programmable reset timer chip (RTC) used in mobile devices and automotive industries. It acts as an agent that ensures power supply is drawn or delivered as required, optimising the efficiency of the process. Furthermore, it also offers protection against overvoltage and undervoltage conditions, preventing any damage to the board when the voltage supplied is too low or too high.In mobile phones, the ADM1068ASTZ is used to monitor and maintain the power delivery between the processor, the display module and many other components of the system. It helps to ensure that the power is delivered in the most efficient manner and prevents costly outages resulting from a particular module being overloaded or from spikes in the voltage. As a result, the batteries of mobile phones last for a longer period of time and the device remains operational for a longer duration than would have been possible without the chip.In the automotive industry, the ADM1068ASTZ is used to monitor the power supply to ensure that the electrical system remains constantly powered and that the engine remains in its peak operating condition. It constantly monitors the power supply voltage and ensures that any changes in the voltage do not result in the system either providing too much or too little power during various processes. As a result, it helps to maintain the engine’s performance and prevent any premature failure of its components due to incorrect power delivery.

How Does the ADM1068ASTZ Work?

The ADM1068ASTZ is an integrated system whose goal is to optimise the power supply to the components of any given system. It relies on its inbuilt voltage switch and an ultra-low power regulator in its design to precisely monitor and control the flow of power.The voltage switch triggers whenever the monitored voltage dips below the set threshold, triggering an alarm to be sent to the on-board processor. The processor then shuts down the system until the voltage is reset. The ultra-low power regulator, on the other hand, keeps the voltage within a predetermined range, maintaining the necessary power supply to the system’s components.The ADM1068ASTZ also features a watchdog timer which guards against any outages resulting from system malfunctions. It sends a signal every predetermined cycle time, ensuring that the system is still functioning. In the event that the cycle time has not been met, the watchdog timer will shut off the power to the system, preventing further damage.

Conclusion

The ADM1068ASTZ is an essential part of any given system, allowing it to operate and perform at its best. It is used in mobile phones and the automotive industry in order to optimise the power delivery, prevent outages resulting from voltage fluctuations, and maintain the engine in its peak operating condition. It utilizes a voltage switch and an ultra-low power regulator to monitor the power supplied and performs calculations to ensure the system continues to work safely and efficiently. It also contains a watchdog timer that monitors the system cycles and shuts off the power supply in case of any malfunction.
