LT3650IMSE-4.2#PBF Application Field and Working Principle

LT3650IMSE-4.2#PBF is a power management IC (PMIC) designed for battery charging applications. It is designed to handle complex current paths with its configurable power pathways. The input and output voltage and current paths are optimized for simple system integration and low component count. The device also features maximum power point tracking (MPPT) for real-time optimization of the power being supplied to the system.The LT3650IMSE-4.2#PBF utilizes advanced power management technologies, which allow it to achieve high efficiency and high power density. It is capable of handling up to 6A of input current and 21V of input voltage. The device also features an adjustable output voltage from 3.7V to 21V, adjustable charging current from 500mA to 6A, and selectable charge mode for Li-ion, LiFePO4, and NiMH batteries. The LT3650IMSE-4.2#PBF allows for several charging modes, such as constant voltage (CV) and constant current (CC) modes. The device uses an internal floating synchronous rectifier (FSSR) to ensure that power losses are minimized when charging in CC mode. Furthermore, it can be used as a stand-alone device or as part of a multi-cell battery pack.The LT3650IMSE-4.2#PBF is ideal for applications such as portable consumer products, power tools, and cordless medical devices. Its integrated protection features help prevent over-temperature, reverse current flow, and over-current conditions. It also includes an adjustable current-limited mode, adjustable pre-charge current, and an adjustable recharge voltage. The LT3650IMSE-4.2#PBF is a great choice for battery charging applications due to its wide input and output voltage and current range, high power density, and integrated protection features. With its MPPT capabilities, it is capable of maximizing the efficiency of the charging process, which helps extend the run-time of the system. Finally, the device is cost effective, making it a great fit for budget conscious applications.
