The S-8264AAJ-I8T1U is a highly efficient Power Management IC (PMIC) in the Battery Management System family, designed for Li-ion battery-based applications. It is a single-chip device that combines an LDO voltage regulator, a linear voltage regulator, and an advanced signal conditioning circuit with high-speed protection functions. This PMIC is easily integrated into other designs, and its features include: a built-in high-precision current monitoring circuit, active cell balancing, and two independent over-voltage and over-current protection functions. Furthermore, the device is designed to minimize power consumption, resulting in a high level of power efficiency.

The S-8264AAJ-I8T1U PMIC is commonly used in applications such as mobile phones, tablets, and other handheld devices that use lithium-ion batteries. It is also used in applications such as portable power banks, electric vehicles, and other applications where battery monitoring and management are needed. This PMIC is particularly well-suited in applications where the protection and safety of the system must not be overlooked, such as remote important equipment, transportation systems and medical systems, where there is a high reliability requirement.

The certified signal processing technology used by this PMIC allows for accurate measuring of cell voltages within any Li-ion battery cell. This allows for a more accurate and reliable battery management system, eliminating the need for additional components, such as external over current protection devices (OCPs), over voltage protection devices (OVPs), and current sensors. This ensures a more efficient and simpler design for the system.

The S-8264AAJ-I8T1U PMIC also features an integrated 3-level over-current protection (OCP), an over-voltage protection (OVP) and an active cell balancing function. This allows the battery state can be monitored accurately, ensuring safer use of the battery and reducing the risk of overcharging or deep discharge. Additionally, the integrated 8-channel analog front-end can monitor each cell individually, allowing for complete cell voltage control. This also makes cell equalization possible to increase time between charge cycles.

The S-8264AAJ-I8T1U PMIC has built-in short protection, so when a short circuit occurs it will quickly shut down the system, preventing the battery from further damage. Additionally, the power output from this PMIC is also relatively low, making it easier to maintain the temperature of the system and ensure a more efficient use of energy.

Overall, the S-8264AAJ-I8T1U PMIC is an excellent choice for any application involving Li-ion battery management, especially in critical applications where reliable and accurate monitoring of the cell is required. With its low power consumption, integrated OCP, OVP, and active cell balancing, as well as its short circuit protection, this PMIC provides a powerful and reliable solution for intergrated battery management.
