It uses an I²C interface for setting charge parameters and reading status, which makes it a good fit for designs that need to adjust the charge profile in firmware rather than with fixed resistors. The part is rated for a 3.7 V battery pack voltage and operates from a supply up to 6 V. Fault protection includes over-temperature and over-voltage shutdowns. ## I²C control and charge current flexibility The I²C interface lets you program the charge current, termination current, and voltage thresholds on the fly. This is useful when the same PCB must support different battery capacities or chemistries across product variants — no resistor swap, just a firmware change. The 2.5 A max charge current suits a single-cell Li-Ion/Polymer battery in a portable device.","metaTitle":"BQ24168YFFR Battery Charger IC, 2.5A Max, I²C, 49-DSBGA","metaDescription":"Texas Instruments BQ24168YFFR single-cell Li-Ion/Polymer charger, 2.5A max charge current, I²C interface, 49-DSBGA package.
