PMIC - Battery Management

Power management integrated circuits (PMICs) are specialized integrated circuits used in devices that require power management functions, including battery management. PMICs manage power sources, efficiently and accurately distribute power, conserve energy, and protect against power surges and outrages. PMICs are often used in applications such as automotive, industrial, and computing systems.The AP9101CAK-AATRG1 is a single-cell Li-ion/Li-polymer battery management integrated circuit specifically designed to support the efficient management of charge and discharge functions for advanced batteries. It integrates a battery protection switch, a high precision voltage regulator, and a smart battery charging controller. The device offers precise charge/discharge control with its high performance 16-bit ADC, and can support up to 6.4V input for Li-ion batteries and 7.4V for Li-Polymer batteries.The AP9101CAK-AATRG1 is specifically designed for advanced Li-ion and Li-polymer based batteries. This includes advanced application fields such as energy harvesting, power storage, healthcare, robotics, wearable devices, automation, high-end consumer electronics and automotive application. Additionally, the device is designed to provide high-precision voltage and current regulation and output power management, as well as dynamic load balancing and boosting, while ensuring a safe and efficient operation.The AP9101CAK-AATRG1 has a wide range of features that enable efficient and secure charge/discharge control. These features include a low quiescent current and high efficiency power regulator, a multi-level safety-protection system, and a charge/discharge precision adaptation to prevent overvoltage and overcurrent conditions.The AP9101CAK-AATRG1 includes several protection mechanisms to ensure secure operation. This includes overvoltage protection, over-temperature degradation, and overcurrent protection for both charge and discharge. This also includes time-limited charge, dynamic current limiting and dynamic input voltage limitation.The AP9101CAK-AATRG1 works in two main stages: charge and discharge. During charging phase, the first factor to consider is the battery’s input voltage. The AP9101CAK-AATRG1 can intake up to 6.4V for Li-ion batteries and 7.4V for Li-Polymer batteries. After that, the device will monitor the battery’s temperature, the current and voltage present, and the voltage of the power source.Once all the parameters are met, the device will activate the charge phase. During this phase, the battery is continuously monitored and controlled to ensure a gradual and secure charge. The AP9101CAK-AATRG1 also works to ensure that the charge is terminated correctly.In discharge phase, the AP9101CAK-AATRG1 can converge to one of three output line types: Discharge, Short Circuit, and Pre-Condition. The discharge line is used for steady state discharge. Meanwhile, the short circuit line is used to reduce the short circuit current in the battery. Finally, the pre-condition line is used to limit the discharge current and prevent over-discharging.Overall, the AP9101CAK-AATRG1 provides a reliable and efficient platform for efficient charge/discharge control of Li-ion/Li-Polymer based batteries. With its wide range of features, high precision voltage regulation, and a multi-level safety-protection system, it ensures secure and efficient operation as required in advanced battery management applications.
