The LTC4065EDC#TRMPBF from Linear Technology is a high-performance, standalone linear charger for single-cell lithium-ion or lithium-polymer batteries. Designed to provide a safe and efficient charging solution, this compact component simplifies the development of portable devices by integrating key features within a small footprint.

This charger is housed in a low-profile (2mm x 2mm) 6-pin DFN package, making it an ideal choice for space-constrained applications. Despite its small size, the LTC4065EDC#TRMPBF comes packed with advanced features such as programmable charge current up to 950mA, a charge current monitor, and automatic recharge.

The device operates over a wide input voltage range from 4.25V to 6.5V, which allows it to be powered from various USB sources and wall adapters. The LTC4065EDC#TRMPBF ensures a safe charging process by incorporating an internal thermal feedback mechanism that regulates the charge current to limit the die temperature during high power operation or high ambient temperature conditions.

Moreover, the LTC4065EDC#TRMPBF features a complete constant-current/constant-voltage charge cycle with preconditioning, which ensures that deeply discharged cells are gently brought up to a safe charging level before applying the full charge current. The charging process is terminated based on a programmable charge termination timer or when the charge current falls below a user-settable level.

To protect the battery and enhance safety, the LTC4065EDC#TRMPBF includes features such as automatic shutdown when the input supply is removed, overvoltage protection, and a charge status output that can drive an external LED to provide visual feedback on the charging process.

In summary, the LTC4065EDC#TRMPBF is a versatile and reliable solution for portable electronics requiring efficient battery management. Its ease of use, combined with a robust set of features, makes it a prime choice for designers looking to enhance the performance and longevity of their battery-powered devices.
