PMIC (Power Management Integrated Circuits) is a type of integrated circuit that is used to regulate and manage power in a variety of different applications. Supervisors, or PMIC Supervisors, are one subset of PMICs that are specifically used to ensure that products are operating within the parameters specified by their design. In this article, we will look at the application field and working principle of one such PMIC Supervisor, the ADM800MARNZ.

Application Field

The ADM800MARNZ is a PMIC supervisor designed to provide system-level load protection and monitoring in a range of applications, such as cellular phones, creative multimedia players, remote sensor nodes, and other low-voltage applications. In such applications, the ADM800MARNZ can help improve system reliability and power savings by monitoring power-on conditions and controlling the power-on sequencing of system-level devices. In addition, it provides an effective way to protect the system against over-currents, under-voltages, brown-outs, and reverse-voltage conditions.

Working Principle

The ADM800MARNZ is designed to monitor the power supply voltage and report back any changes in real time. It is typically powered by either a 3V or 5V supply, but it can also be powered from other sources. It has configurable thresholds for both over-voltage and under-voltage signals that enable it to detect any sudden changes in the supply voltage and report the result back to the system. It also has a built-in timer that can be programmed to specific time periods. This timer ensures that the device does not remain in an over-voltage or under-voltage condition for an extended period of time. The ADM800MARNZ also features a brown-out detector that is used to detect and prevent system operations in cases when the supply voltage drops below certain thresholds.

In addition, the ADM800MARNZ can be used to provide system-level load protection by monitoring the current being drawn by the load and reporting back any changes. This load protection feature helps protect the system against any sudden changes in load that could cause the system to fail. The ADM800MARNZ also features a reverse-voltage protection feature that helps protect the system against any spurious voltage conditions.

Overall, the ADM800MARNZ is a PMIC supervisor designed to provide system-level load protection and monitoring for a variety of applications. It offers a wide range of features designed to improve system reliability and power savings, as well as protect the system from over-voltage, under-voltage, brown-out, and reverse-voltage conditions.
