PMIC - Supervisors are a type of integrated circuit designed to monitor and regulate the voltage signals sent between a power supply and a power-consuming, or powered, device. The ADM1266ACPZ is an example of aPMIC - Supervisor specifically tailored for portable, battery-powered applications. By keeping voltage levels within certain constraints, the ADM1266ACPZ ensures that the electrical signals sent to and from the powered device are in line with what the device needs. Knowing its application field and understanding the working principles of the ADM1266ACPZ are important considerations when designing a portable power solution.

Application Field of the ADM1266ACPZ

The ADM1266ACPZ PMIC - Supervisor is specifically designed for use in portable applications that run on battery power, such as mobile devices and portable medical instruments. It is suitable for multiplexed power designs, including those limited to a few battery cells in a series, as well as complex multiple parallel battery solutions like those used in autonomous robots and unmanned aerial vehicles. The integrated circuit is an ideal solution for these applications due to its low quiescent current and ability to support up to six battery cells or multiple devices drawing power from different sources.

ADM1266ACPZ Working Principle

The ADM1266ACPZ PMIC - Supervisor is designed to work by monitoring and controlling the voltage levels sent to and from the battery-powered device. This is done using a buck-boost switching regulator, which is a type of linear regulator that switches between buck and boost conversion based on the voltage levels. When the voltage is below the set threshold, the buck-boost regulator will convert the voltage up to the necessary level. On the other hand, when the voltage is above the set threshold, the regulator will convert it down to the required level. This ensures that the voltage sent to and from the powered device is kept within the prescribed range, thus avoiding overvoltage or undervoltage situations.

In addition to the buck-boost regulator, the ADM1266ACPZ also incorporates a number of other features designed to ensure reliable power delivery. Most notable is the fact that it supports up to six battery cells, making it ideal for multiplexed power designs. The IC also comes with a host of built-in protection features to guard against short-circuits and over-currents, as well as over-temperature conditions. Finally, the PMIC - Supervisor is designed to detect charge conditions on the battery cells, thus allowing for optimized charging performance.

Conclusion

The ADM1266ACPZ PMIC - Supervisor is an ideal solution for portable applications that require reliable power delivery. Its ability to monitor and control the voltage levels sent to and from the powered device ensures that the electronics remain safe, while the buck-boost regulator helps to maintain the required voltage levels even under changing conditions. Furthermore, its support for up to six battery cells and built-in protection features make it suitable for complex multiple parallel battery solutions. Knowing the application field and understanding the working principles of this PMIC - Supervisor is critical when it comes to designing efficient and reliable system for portable applications.
