The Texas Instruments BQ24270YFFR is a single-cell Lithium Ion battery charger IC in a 49-DSBGA (2.8x2.8) package. The I²C bus lets the host system set the charge current dynamically — useful for thermal throttling or adjusting charge rate based on input power availability.
Protection and operating range
On-chip fault protection covers over-temperature, over-voltage, and short-circuit conditions, reducing the need for external monitoring components. The surface-mount DSBGA package suits compact portable equipment where board area is tight.
