The LT3652EDD#PBF is a fully integrated power management integrated circuit (PMIC) used for lithium-ion (Li-ion) battery charging. It has several integrated features that ensure safe and reliable operation, so that it can be used in a wide range of applications. This PMIC is categorized under Battery Chargers and its key features, application field and working principle are discussed in the following sections.

Features

The LT3652EDD#PBF has two key features that make it suitable for use in Li-ion battery charging applications. The first feature is its flexible charge profile, which can be adapted to different types of Li-ion batteries and/or conditions. This feature includes temperature protection, safety timer, charging current control and charge termination current control. By using this feature, users can tailor the charging profile to fit their Li-ion batteries and optimize the charging performance.

The second key feature is its smart input power path. It allows users to dynamically adjust the input source depending on the available power source. Users can select the input power source, such as battery, power adapter, charger or USB, and adjust the input voltage, current and logic levels accordingly. This ensures an optimal charging process and efficient power management.

Application Field

The LT3652EDD#PBF is suitable for Li-ion battery charging applications. It is widely used in portable and wireless applications such as laptops, smartphones, cameras, wearables and tablets. It is also used in automotive, industrial and medical applications. Due to its integrated features, it can easily meet the demanding requirements of these applications.

Working Principle

The LT3652EDD#PBF is a charge-only battery charger for Li-ion batteries. Battery charging is controlled by an internal charge controller that monitors the battery voltage and current. During the charging process, the charge controller adapts the charging profile depending on the battery temperature, voltage, current and other conditions. Once the battery is full, the charge controller stops the charging process to prevent overcharging of the battery.

The LT3652EDD#PBF also has input power path control logic which detects the available power source and switches automatically between input sources. This ensures that the charger is powered by the most appropriate source and that power is optimized.

Conclusion

The LT3652EDD#PBF is a fully integrated PMIC used for Li-ion battery charging applications. It has several features, such as flexible charge profile and smart input power path to optimize power management and battery charging. This PMIC can be used for a wide range of applications, such as portable and wireless devices, automotive, industrial and medical applications.
