Single-cell Li-Ion charger with I²C control
The Texas Instruments BQ24260SYFFR is a single-cell Li-Ion battery charger IC that delivers a programmable charge current up to 3A via an I²C interface. It integrates over-temperature and over-voltage fault protection, making it suitable for portable devices where space is tight and charging needs precise control.
3A charge current and 10V supply ceiling
The 3A maximum charge current supports fast charging of single-cell Li-Ion packs with a 3.6V battery voltage. The 10V supply maximum means the input can come from a standard 5V USB port or a 9V adapter without external regulation, as long as the input stays under 10V.

36-DSBGA package — layout considerations
The 36-DSBGA package measures 2.63x2.46 mm with a 0.5 mm ball pitch. Surface-mount assembly requires a solder mask defined pad with a 0.25 mm opening and a 0.3 mm NSMD pad. The small footprint demands a 4-layer PCB for fan-out of the I²C, power, and battery connections.
