Introduction

The S-8213AAC-I6T1U is a Power Management Integrated Circuit (PMIC) and Battery Management System from SANYO Electric Co., Ltd. It is designed for general purpose applications and for use with highly integrated mobile devices such as smartphones and tablets.

The S-8213AAC-I6T1U provides battery charging functionality for small Li-ion or Li-polymer batteries. It operates up to 6V and can handle currents of up to 1.5A. It provides a range of protection features, including overcharge and undervoltage protection, and can be used to optimize the life of the battery.

Application Field

The S-8213AAC-I6T1U is mostly used in smartphone, tablets and other mobile devices, which require a small power management and battery management system. It is suited for applications with limited space and weight restrictions, and is highly efficient.

The S-8213AAC-I6T1U is used to control the charging process of Li-ion and Li-polymer batteries. It offers multiple protection functions, including overcharge protection, undervoltage protection, and overdischarge protection. It is capable of charging single cells as well as multi-cell battery packs with up to six cells in series.

The device can be used to optimize the lifetime and performance of lithium ion batteries by controlling the charging process in real time. It is also capable of supporting fast charging, allowing battery packs to be fully charged in a short time.

The circuit also offers integrated low RDS(on) protection MOSFETs for load control and can be controlled either by an external microcontroller or by a host processor.

Working Principle

The S-8213AAC-I6T1U uses a two-stage charging process. The first stage is a Constant Current (CC) charge, in which the current is maintained constant until the battery voltage reaches a predetermined limit set by the user. During this stage, the S-8213AAC-I6T1U is capable of efficiently charging the battery in a short amount of time.

The second stage is a Constant Voltage (CV) charge, in which the voltage is kept constant until the current drops to a predetermined level. This stage is used to top off the battery and ensure the cells are completely charged. The device also offers temperature protection, which prevents overcharging and potential cell damage when the temperature gets too high.

In addition, the S-8213AAC-I6T1U offers adjustable overcharge protection and overdischarge protection as well as pre-charge current detection. The device also offers a broad range of protection features, such as overvoltage, undervoltage, and overcurrent.

The device can be programmed to support different Li-ion and Li-polymer chemistries, allowing for versatile battery charging when dealing with different cell types. Furthermore, on-chip control logic allows for the device to be used in multiple configurations.

The S-8213AAC-I6T1U is a highly integrated and efficient power management and battery management unit, making it an ideal choice for a wide range of battery-powered devices.
