What are the lithium-ion battery power management IC chips and charging management chips?

Lithium-ion battery power management IC chip Li-ion battery power management chip is a chip that is responsible for the conversion, distribution, detection and other power management responsibilities of electrical energy in the electronic equipment system. It is important to identify the power supply amplitude of the CPU, and the corresponding The short moment wave drives the subsequent circuit for power output. Commonly used power management chips include HIP6301, IS6537, RT9237, ADP3168, KA7500, TL494, etc. Li-ion battery power management chips have a wide range of applications. The development of power management chips is of great significance for improving the performance of the whole machine. The choice of power management chips is directly related to the needs of the system, and the development of digital power management chips needs to overcome cost difficulties. . All electronic devices have power sources, but different systems have different requirements for power sources. In order to give full play to the best performance of the electronic system, it is necessary to choose the most suitable power management method. To some extent, it is precisely because of the massive development of lithium-ion battery power management IC chips that power semiconductors have been renamed power management semiconductors. It is precisely because so many integrated circuits (ICs) have entered the power supply field that people call more power management the current power technology. Among these power management ICs, voltage regulation ICs are the fastest growing and most productive part. Various power management ICs are basically related to some related applications, so for different applications, more types of devices can be listed. The technical trend of lithium-ion battery power management is high efficiency, low power consumption, and intelligence. What is the lithium-ion battery charge management chip? 1.
