X5165P-2.7

PMIC - Supervisors are one type of integrated circuits (IC) that perform critical operations on the voltage and current signals of a system. It is the overseer of all power communication throughout a system by supplying power, monitoring, controlling and protecting the power supply. The X5165P-2.7 is a complex PMIC where its two main functions are to identify real-time high-side current and voltage readings on differential high-side current sensing techniques, and to protect the IC from reverse battery protection. This application field and its working principles will be discussed in full below.

Application Field of X5165P-2.7

The X5165P-2.7 is a high-side power supervisor IC designed for use with rechargeable lithium-ion (Li-ion) and Lithium-Iron-Phosphate (LFE) batteries. Its primary application field is for use with portable consumer electronics such as laptops, tablets, smart phones, and wearable devices. Its ability to monitor, control, and protect the power supply makes it ideal for these low-power applications where long battery life is needed.

Working Principle of X5165P-2.7

The X5165P-2.7 is a highly integrated supervisor controller consisting of three major functions. The first function is the sensing of voltage and current on its differential high-side current sensing techniques. It can accurately measure voltage and current levels on high-side lines, allowing for greater system efficiency and reliability. It can also detect if the battery voltage is dropping, alerting the system when a battery needs to be recharged or replaced.The second major function of the X5165P-2.7 is to protect its IC during operation by using its reverse battery protection capability. It can detect when the voltage on the battery is reversed and shut down the system before any damage can occur.The final major function of the X5165P-2.7 is the temperature monitoring and temperature protection. It can accurately measure temperature on both the high-side and the low-side of the system, in addition to controlling the temperature, allowing the system to operate within its safety parameters. This temperature monitoring helps to ensure that the system is not exposed to excessive heat while in operation.

Conclusion

The X5165P-2.7 is a complex PMIC that is often used in portable consumer electronics applications. Its three main functions are to accurately monitor voltage and current levels, to protect the IC from reverse battery protection and to control and monitor temperatures in order to prevent excessive heat. The X5165P-2.7 provides a great deal of reliable power supervision in the small and low-power system.
