LT3652EMSE#TRPBF - Power Tracking 2A Battery Charger

The LT3652EMSE#TRPBF is a highly sophisticated power tracking battery charger designed by Linear Technology for modern electronic applications. It is specifically tailored for charging lithium-ion/polymer batteries from a variety of power sources, including solar panels and wind turbines. The device is capable of delivering up to 2A of continuous charge current, which can be adjusted via a resistor to suit the needs of different battery sizes and chemistries.

One of the standout features of the LT3652EMSE#TRPBF is its PowerPath control, which allows the chip to provide power to the system load while simultaneously charging the battery. This feature ensures that even when the input power is limited, system operation remains uninterrupted. The charger operates with an input voltage range of 4.95V to 32V, which accommodates a wide array of power sources, including poorly regulated sources.

The charging process is managed by an intelligent algorithm that starts with a preconditioning phase for deeply discharged batteries, followed by a constant-current phase for rapid charging, and then transitions to a constant-voltage phase to fully charge the battery. The charging parameters and battery chemistry settings are programmable through pin configurations, providing flexibility and precision to the user.

The LT3652EMSE#TRPBF also features an array of protection mechanisms. It includes thermal regulation to prevent overheating during the charging process, and it terminates the charge cycle when the charge current falls below a user-configurable level. Moreover, the device has an automatic recharge feature, which initiates a new charging cycle if the battery voltage falls below a certain threshold.

With its small footprint, the LT3652EMSE#TRPBF comes in a compact 12-lead MSOP package, making it an ideal choice for space-constrained applications. Its robust design ensures high reliability and performance, making it an excellent choice for portable devices, solar-powered systems, and other applications requiring efficient and reliable battery charging solutions.
