The BQ24187YFFR is an integrated circuit (IC) component developed by Texas Instruments. It is a high-efficiency, single-cell, USB-compliant battery charger designed specifically for portable applications. This IC has various key features that make it highly suitable for battery charging applications.
One of the primary features of the BQ24187YFFR is its ability to charge a single-cell Li-Ion, Li-Po, or Li-FePO4 battery pack from a USB port or an adapter. This charging capability makes it widely applicable in portable electronic devices such as smartphones, tablets, and portable audio players.
To ensure optimal charging efficiency, the BQ24187YFFR integrates a synchronous switching power supply controller. This controller provides high power conversion efficiency and helps in reducing heat dissipation during charging, thereby improving overall system efficiency. Additionally, the IC supports input voltage regulation, which allows it to regulate the charging current independently of the USB voltage, enabling flexible charging configurations.
The BQ24187YFFR features an advanced power path management system that enables the system to operate even when the battery is deeply discharged or removed. This feature minimizes system downtime and allows for uninterrupted usage of the device while charging. Furthermore, the IC incorporates dynamic power management, which intelligently monitors the system load and battery voltage to optimize charging efficiency.
