Introduction

The S-8230AAE-I6T1U is a multiple output synchronous step-down DC-DC converter and battery protection IC that includes the necessary protection functions and fault management for Li-Polymer and Li-Ion battery packs and provides many fixed output voltage options for the system design. It is designed to provide designers with a total Li-ion/Li-Polymer battery protection and management solution and simplifies the development of systems incorporating such power sources.

Application Field

The S-8230AAE-I6T1U application field is mainly used in the design of the lithium ion battery packs. It is a perfect combination of protection, charging and discharging, that is, it has functions such as cell balance, over current protection, over voltage protection and reverse protection. Its output voltage can be set to the output voltage of the system, and some optional output voltages are also available.

Working Principle

The S-8230AAE-I6T1U is composed of a voltage regulation loop and a protection loop. In the voltage regulation loop, the system control chip determines the regulation output by adjusting the switching times and duty cycles of the high- and low-side MOSFETs. Next, in the protection loop, the system compares the power information of the battery, such as the current, the voltage, and the charge and discharge status, to the thresholds set in advance by the OTP. Under this condition, the system will promptly shut down when the cell voltage is overcharged or over discharged; when the short circuit of the battery is detected, the system will trigger the alarm and stop the load current in time.

Summary

In conclusion, the S-8230AAE-I6T1U is particularly suitable for lithium ion battery protection and management solutions and can provide multiple output voltage options and functions such as cell balance, over current protection, over voltage protection, and reverse protection. It simplifies the development of systems that use Li-ion/Li-Polymer battery packs.
