The BQ24262YFFT is an integrated circuit (IC) component developed by Texas Instruments. It is a highly integrated single-cell Li-ion battery charger with an input voltage range of 3.9V to 6.2V. This device incorporates all the necessary charging and safety features required for efficient charging of Li-ion batteries.
One of the key features of the BQ24262YFFT is its support for USB On-The-Go (OTG) functionality. This feature allows the device to act as both a charger and a power source, providing power to the system without draining the battery. It can switch seamlessly between the charger and OTG roles, enabling simultaneous battery charging and system power supply.
The BQ24262YFFT offers battery-friendly charging with a highly configurable charge current up to 2A. This flexibility allows it to cater to a wide range of battery capacities and charging scenarios. The device also supports I2C interface, which enables communication with a host system for configuring charging parameters and monitoring battery status.
With advanced power path management, the BQ24262YFFT ensures uninterrupted power supply to the system, even during battery charging. This capability is particularly useful in applications where the battery is not capable of delivering the required load current, such as when the battery capacity is low or during peak system power demand.
The IC incorporates several safety features to protect both the battery and the charging system
