The LTC3110IUF#PBF is a Battery Charger IC that is specifically designed for powering linear lithium-ion battery systems, such as cylindrical, prismatic, and polymer batteries. The IC integrates most of the features required to support a wide range of Li-ion battery charging scenarios. The IC offers ultra-fast input and output current regulation as well as a complete range of safety and monitoring features. The IC also supports various battery charging algorithms, including trickle charge, fast charge, and charge termination, to optimize the performance of the Li-ion battery system.

The LTC3110IUF#PBF is built on a proprietary architecture that combines a low-noise synchronous buck regulator with a low quiescent current linear charger. This enables the LTC3110IUF#PBF to simultaneously power loads, such as analog and digital circuits, while keeping the battery system balanced by maintaining the regulated battery charge current. The highly flexible architecture of the LTC3110IUF#PBF also allows it to accommodate a wide range of battery chemistries and charge currents.

The LTC3110IUF#PBF is designed for single cell applications, such as portable consumer electronics. It can operate from input sources of 6V to 28V and provides up to 0.8A buck regulator current and 1A linear charger current. The IC is protected by eight-level overvoltage, overcurrent, and overtemperature protections. It also has various battery monitoring features, such as voltage, temperature, and charge-termination detectors.

The LTC3110IUF#PBF features an adjustable charge current limit and temperature profile, as well as an adjustable fast-charge voltage. It also features a three-state charge timer that can be programmed to terminate the charge cycle after a pre-set time. The IC has a comprehensive set of monitoring features, such as voltage, current, temperature, and current-flow detection.

For safety and reliability, the LTC3110IUF#PBF is equipped with forced-shutdown and current-limit overcurrent protections. It also has an adjustable thermal shutdown point that automatically shuts down the battery charger if the temperature reaches the programmed limit. The IC also has an adjustable trickle charge mode that prevents the battery from overcharging.

Overall, the LTC3110IUF#PBF is an ideal solution for applications that require reliable and efficient charging of Li-ion batteries. Its advanced feature set, including adjustable charge current limit, temperature profile, fast-charge voltage, charge timer, safety, battery monitoring, and thermal shutdown, makes it an excellent choice for powering high-end portable consumer electronics applications.
