BQ25898CYFFT Integrated Circuits (ICs)

As one of the high performance power management ICs in Texas Instruments’ portfolio, the BQ25898CYFFT offers a wide range of applications and convenience to a broad scope of industries. With the ability to charging three different battery chemistries at the same time - Li-Ion, Li-Polymer and Li-FePO4 - the BQ25898CYFFT allows a user to charge and manage batteries effortlessly in a single-cell configuration. Additionally, the BQ25898CYFFT offers integrated features and functions that allow for improved system performance such as charge and discharge termination, temperature monitoring, and fast charging.

The BQ25898CYFFT, classified as a PMIC - Battery Charger, has a variety of features and functions that make it a powerful choice for many different applications. The current sense architecture allows for precise control over the charge current, charge voltage and charge termination during charging. Fast charging support is also added, providing up to 1.5A of charging current. This allows for a fast charge to the battery and a reduced charging time, improving user experience.

Temperature monitoring is also a key feature, this allows for precise control of the battery temperature during charging. The battery temperature is monitored continuously, allowing the system to take corrective action when the temperature deviates from the desired temperature range. The BQ25898CYFFT also allows for pre-charge and over-current protection, which helps to prevent thermal runaway and protect the system from short circuits.

In addition, the BQ25898CYFFT offers integrated flexibility and programmability to the user, allowing for easier integration into an application. Buck-boost and gain control are some of the features that can be adjusted and tuned by the user. Specifically, the buck-boost provides power conversion between Input and Output Voltage to maintain battery voltage and current within a certain range. This is beneficial for applications that require high efficiency and low power consumption. Furthermore, with adjustable gain control, the output current can be controlled according to load requirements.

By utilizing features such as fast charging, temperature monitoring, flexible programmability, and additional safety features, the BQ25898CYFFT is a great choice for battery charging applications. Texas Instruments’ provides a wide range of support throughout the design process, providing technical resources and field-applications expertise to optimize the design and guarantee the best performance.
