It provides several functions such as detection of overcharging, overdischarging, charge/discharge suppresses, and cell balancing. This device is suitable for use in a wide range of applications, including portable and industrial battery packs. The S-8215AAB-I8T1U is powered by a single cells (1S battery) and includes an 8-bit MCU for the interface communication.

Application Field

The S-8215AAB-I8T1U battery management IC is suitable for a wide range of applications. These include portable/industrial battery packs, hand-held and mobile products, wearables, and remote monitoring systems. Its features makes it suitable for applications where accurate over-charging protection is needed. It can be used in combination with PMICs and other battery management ICs to distribute the power and protect the battery.

The S-8215AAB-I8T1U provides several functions, such as overcharging, overdischarging, and cell balancing. This makes it ideal for use in safety-sensitive applications, such as medical and automotive. It can also be used in applications requiring high accuracy, such as charging and discharging of Li-ion batteries.

The S-8215AAB-I8T1U is powered by a single cell (1S battery) and offers a special feature called ADC-L (Analog to Digital Converter-Low). This feature allows it to accurately measure the voltage of the battery and provide information about the state of charge. It also offers low-power operation, making it suitable for use in battery powered applications.

Working Principle

The S-8215AAB-I8T1U works by monitoring the battery voltage. When the voltage is too high, it will turn off the charging current and protect the battery from overcharging. It also works with a cell balancing circuit to distribute the charge evenly across all cells in the battery pack.

The S-8215AAB-I8T1U also works with a charge/discharge gate FET in order to suppress the current flow when the battery is either charging or discharging. This allows for improved protection against overcharging and overdischarging.

The S-8215AAB-I8T1U works with a MCU to provide communications between the battery management IC and the host system. This allows the battery management system to communicate with the host system via a serial interface. The MCU also provides the data logging and reporting features.

The S-8215AAB-I8T1U also features an Enhanced Register Mode which allows it to store a set of registers. This can be used to store configuration data, such as the charging and discharging currents, as well as the cell balancing parameters.

In summary, the S-8215AAB-I8T1U is a battery management IC designed to provide accurate over-charging protection in lithium-ion battery-based systems. It provides several functions, such as detection of overcharging, overdischarging, charge/discharge suppression, and cell balancing. This makes it suitable for use in safety-sensitive applications, such as medical and automotive, as well as applications requiring high accuracy.
