The Texas Instruments BQ24271YFFT is a single-cell Li-Ion battery charger with an I²C interface that lets the host microcontroller set the charge current up to 1.5 A.
Built-in fault protection covers over-temperature, over-voltage, and short-circuit conditions.
The maximum charge current is 1.5 A, and it is programmable via the I²C interface. The host sets the current level, so the same charger IC can be used across multiple battery sizes by changing the firmware register value.
