Power Management Integrated Circuit (PMIC) devices like the S-8209ABA-I8T1U are playing a critical role in the latest high-performance applications in cellular, IoT, wearable, and battery management applications. The S-8209ABA-I8T1U, called hereon as “S8209”, is a battery management integrated circuit (BMIC) from Sunplus. This BMIC includes charger, buck-boost voltage regulator, fuel gauge and monitoring units. It is designed in Sunpower’s 0.13um advanced BiCMOS process for optimal performance.

S8209 is primarily a system, power control and monitor. It is specifically optimized for managing the power of system that requires external, single-cell lithium-ion or lithium-polymer battery. It sets up a bridge between the Li-ion battery to the system, providing a continuous power supply, battery protection and data communication interface.

The features of S8209 include low DCR current sensing, switched mode power supply (SMPS) and robust protection. Its advanced power consumption management techniques significantly extend the battery life, while its fast switching times enable high-performance power management and control. In addition, the S8209 comes with support for a wide range of input sources such as USB, AC adapter and battery inputs, allowing for flexible power sources.

The S8209 is designed to provide a number of innovative features intended to maximize efficiency and regulate charge/discharge of the Li-ion battery. In addition to power-on current protection, the charger output is also opposed to an inverting coulomb counting signal. This signal is further used to accurately monitor battery levels and precisely control the charge/discharge rates. Furthermore, the different charge/discharge rates of the Li-ion battery can be monitored and controlled to maximize efficiency and extend battery life. An alternative input option is supported, enabling the back-up battery to be charged in the event of power failure.

Finally, the S8209 includes a DC-DC buck boost voltage regulator circuit. This circuit is capable of adjusting the voltage to precisely match the system supply voltage, by automatically controlling the voltage step down for low voltage, and step up for higher voltage battery conditions. The S8209 also provides a holder for low power current of up to 5mA for embedded applications.

In summary, the S8209 BMIC from Sunpower provides scalability, robust protection, flexibility, high performance and power conservation. This product is ideal for applications that require Li-ion battery management, large current range power control, and distributed power management. It is extremely suitable for embedded systems and portable products, providing efficient and reliable energy management.
