LTC4068XEDD-4.2#TRPBF - Standalone Linear Li-Ion Battery Charger with Thermal Regulation

The LTC4068XEDD-4.2#TRPBF is a highly integrated standalone linear lithium-ion battery charger produced by Linear Technology, which is now part of Analog Devices. This compact and efficient charging solution is designed to simplify the charging process for single-cell lithium-ion batteries in a wide range of portable electronic devices.

Featuring a programmable charge current up to 1A, the LTC4068XEDD-4.2#TRPBF can rapidly charge batteries from a variety of USB-compliant sources or from a wall adapter. Its small footprint, made possible by the DFN package, allows it to be seamlessly integrated into space-constrained applications, making it an ideal choice for portable devices such as medical equipment, personal audio/video players, digital cameras, and smartphones.

The LTC4068XEDD-4.2#TRPBF incorporates an internal thermal feedback mechanism that optimizes the charge rate for any given environmental condition. This thermal regulation feature ensures that the charger maintains a safe temperature, preventing overheating and enhancing the safety and longevity of both the charger and the battery being charged.

Additional features include an automatic recharge function, which initiates a new charging cycle when the battery voltage falls below a preset threshold, ensuring that the battery remains fully charged. The device also provides a charge termination feature, which stops the charging process once the battery reaches its final float voltage, safeguarding against overcharging.

The LTC4068XEDD-4.2#TRPBF offers a range of safety features such as overvoltage protection, which prevents damage to the battery if the input voltage exceeds a safe threshold, and a C/10 charge termination indicator, which provides a clear indication of the end of the charge cycle.

Overall, the LTC4068XEDD-4.2#TRPBF from Linear Technology stands out as a reliable and user-friendly charging solution that ensures safe, efficient, and fast charging for lithium-ion batteries, making it an excellent choice for designers looking to enhance the power management capabilities of their portable electronic devices.
