S-8264AAI-I8T1U

PMIC - Battery Management covers an array of techniques and technologies that are used to manage the charge and discharge of a battery system. This helps increase the lifetime and performance of the battery, and to ensure the battery is operated within the safe operating boundaries set by the manufacturer. The S-8264AAI-I8T1U is a Power Management IC (PMIC) for lithium-ion batteries that helps to manage their charge and discharge. It offers dual input operation, low quiescent current, fast system start-up, accurate over-discharge prevention, and over-charge protection.

The S-8264AAI-I8T1U utilizes a sophisticated proprietary algorithm to monitor the charge and discharge current of the battery system, as well as the voltage applied to the battery system. With this information, the PMIC can control the charge and discharge cycle of the battery accurately and safely. The PMIC also offers a number of user-selectable parameters that can be employed to customize the charge and discharge profile of the system to suit different applications.

The S-8264AAI-I8T1U is mainly used to provide a safe charging and discharging environment for Li-Ion battery applications. The device is suitable for use in a wide range of consumer and industrial products, from laptop computers and cell phones to hybrid electric vehicles and industrial backup systems.

The working principle of the S-8264AAI-I8T1U is based on the four stages of a typical Li-Ion charging cycle: pre-charge, constant current charge, constant voltage charge, and top-off. In the pre-charge stage, the PMIC senses the presence of a battery in the system and starts charging it with a controlled current limit. This is done to quickly and safely bring the battery cell voltage up to a suitable level.

The PMIC then enters the constant current charging stage, and maintains a constant charging current until the battery voltage reaches a preset threshold. When this voltage is reached, the PMIC switches to the constant voltage charging stage and continues to supply the battery with a voltage below the specified threshold. The PMIC then enters the top-off stage, in which it reduces the charging current as the battery nears its full capacity.

The S-8264AAI-I8T1U also offers additional features such as a temperature monitor, over-discharge detection, over-charge detection, and battery balancing. The temperature monitor helps the PMIC to detect the temperature of the battery during charging and discharging to ensure safe operation. The over-discharge and over-charge detection features are used to protect the battery from excessive current and voltage levels, respectively. The battery balancing feature helps balance the voltage of each cell in the battery pack, allowing the battery to gain maximum efficiency.

In addition, the S-8264AAI-I8T1U can be used to monitor the health of the battery pack in real time. This is done by measuring the cell voltage of each battery pack and sending data back to a host system. The PMIC also offers several safety features such as a low voltage disconnection and an over-temperature protection. These features help prevent damage to the battery pack and keep it safe during use.

The S-8264AAI-I8T1U is a versatile and efficient PMIC for Li-Ion battery applications. It offers a safe and reliable charging and discharging environment for the battery and helps to increase the battery performance and lifetime. With its sophisticated proprietary algorithm and user-selectable parameters, the S-8264AAI-I8T1U can be used in a wide range of consumer and industrial products for safe and reliable battery management.
