Benefits of LTC4009CUF-2#PBF

The LTC4009CUF-2#PBF is controlled by an internal Digital Signal Processor (DSP) and can work with a wide input voltage range, allowing it to be used in many devices. Because it is powered by a two-step charging algorithm, it eliminates the need for multiple cells or stages of charging, and it provides the ability to adjust the charge current depending on the application. Additionally, the device features over-temperature protection, short-circuit protection, and low-temperature protection.

LTC4009CUF-2#PBF Application Field

The LTC4009CUF-2#PBF is suitable for use in a wide range of applications, with its ability to support up to 12V input voltage, up to 80V charge voltage and up to 7A charge current. This makes it ideal for high efficiency applications, such as notebooks, tablets, cellular phones, personal digital assistants, and more.

Working Principle

The LTC4009CUF-2#PBF utilizes a two-step charging algorithm to ensure that the battery is effectively and safely charged. In the first step, the battery is quickly charged up to the nominal voltage and current set point. After the battery is charged to the set point, the device slowly charges the remaining capacity and slowly reduces the charge current until the battery is completely charged. This ensures that the battery is not overcharged, avoiding damage to the battery or cell damage.

Conclusion

The LTC4009CUF-2#PBF is a powerful and reliable Battery Charger from Linear Technology Corporation. With its advanced power management, integrated protection circuitry and wide input voltage range, it is ideal for high efficiency applications such as notebooks, tablets, cellular phones, personal digital assistants, and more. The two-step charging algorithm allows for safe charging at high efficiency, ensuring that the battery is not overcharged and the battery life is maximized.
