PMIC – Battery Management

With the rapid development of digital devices, the demand of power efficiency and stability has also been continuously improved. To ensure the normal operation of electronic devices and optimize their performance, PMICs, as an important part of the power architecture, come into being. Among them, S-8264AAA-T8T1G PMIC is a popular product which applies to a variety of devices and has high performance. This paper will discuss the application field and working principle of S-8264AAA-T8T1G PMIC in depth.

1. Application Field

S-8264AAA-T8T1G PMIC adopts an 8-channel safe power system which supports up to 8 independent power supply outputs for different components. Each channel supports output to 1.5A with wide input voltage range from 3V to 5.5V. The stable performance realized by its high voltage accuracy ensures system safety and stability. Furthermore it integrates various protection functions such as Overcurrent Protection (OCP), Undervoltage Protection(UVP), Over Temperature Protection, Short-circuit protection and Battery Over Charge Prevention(BOTP), which provide safety guarantee to the whole system and improve its performance.

In addition, S-8264AAA-T8T1G PMIC is suitable for a wide range of applications such as Smartphones and Tablets, wearable devices, VR devices, IoT devices, human machine interface boards, automotive and industrial computation systems, etc.

2. Working Principle

The working principle of S-8264AAA-T8T1G PMIC is to convert a wide range of input voltage to stable and independent voltage output for different components. Take a 4-channel setup as an example:

Firstly, a buck converter is used to convert a 5V input into lower regulated output of 1.8V, and then two LDOs, 3.3V and 1.8V, convert the output into 3.3V and 1.8V respectively. And at the same time, the OCP starts converting back the excessive current from the buck converter, 4.2V buck converter and 4.2V LDO, so that the system will not be damaged by short-circuit and over current. Finally, BOTP is used to prevent over charging of the battery and achieve a complete and stable system.

3. Conclusion

S-8264AAA-T8T1G is a multi-channel PMIC with wide application fields and good performance. It supports up to 8 independent power supply outputs with high voltage accuracy, wide input voltage range, Overcurrent Protection(OCP) features, and Battery Over Charge Prevention(BOTP) function. The working principle of S-8264AAA-T8T1G PMIC is to convert a wide range of input voltage to stable and independent output for different components. Thus, it is a very efficient and reliable PMIC with many advantages.
