Efficient and advanced power supplies are essential components for a wide range of applications and products. Power Management Integrated Circuits (PMICs) are designed to provide power solutions for a variety of components and systems, from desktop PCs to handheld devices. Battery chargers are one type of specialized PMIC that are designed to power and manage a system’s battery. The LT1769IFE#PBF is one of TI’s battery chargers that is designed for use in a range of applications.
Application Field
The LT1769IFE#PBF is a linear battery charger IC specifically designed for linear charging of Lithium-Ion (Li-Ion) and Lithium-Ion-Phosphate (LiFePO4) battery packs. This charger is suitable for portable media players, GPS receivers and other portable applications. It features a high power-to-space ratio and low quiescent current, making it an ideal choice for space-constrained designs. The LT1769IFE#PBF is also able to provide up to 600mA of charge current, making it suitable for high-capacity battery packs.
The LT1769IFE#PBF is also suitable for use in applications where battery protection is required. It can detect over-charge, over-discharge and over-temperature conditions, providing protection to the battery and system. Additionally, the integrated safety timer ends the charge cycle at a predetermined timeout, preventing over-charging of the battery. These features make the LT1769IFE#PBF an ideal choice for applications where safety is paramount.
Working Principle
The LT1769IFE#PBF is a constant current / constant voltage (CC/CV) battery charger. This charger is based on the Buck topology, operating in the discontinuous current mode. It features internal current sensing, eliminating the need for external sense resistors. This means that it is able to provide higher charging current than conventional linear battery chargers, with lower power loss. The LT1769IFE#PBF also features integrated short-circuit protection and thermal protection, further improving system safety.
The LT1769IFE#PBF is designed to charge a battery from an input voltage of 4.5V to 36V. It is capable of cutting off the input power at any time if the input voltage is too high or too low, thus preventing damage to the system. Additionally, this charger is able to regulate the output voltage to a maximum of 4.2V, ensuring the battery is at a safe charging level.
The LT1769IFE#PBF also features an adjustable charge current. The charge current can be set using an external resistor, allowing a wide range of current settings. Additionally, the LT1769IFE#PBF also features integrated cell balancing, which ensures each cell in a multi-cell battery pack is charged evenly. This feature helps increase the life of the battery and provides greater system safety.
Conclusion
The LT1769IFE#PBF is a linear battery charger IC designed for use in a wide range of applications. It is specifically designed for charging Lithium-Ion and Lithium-Ion-Phosphate battery packs, and is able to provide up to 600mA of charge current. This charger features integrated current sensing and cell balancing, as well as over-temperature and over-voltage protection. It is the ideal choice for applications where safety and efficiency are paramount.
