Battery Chargers Procurement Notes

Verify the specific suffix YFFT against official Texas Instruments documentation to confirm the reel packaging quantity and tape-and-reel specifications. Ensure compatibility with the required operating temperature range and I2C address settings before finalizing procurement orders.

Battery Chargers Selection Notes

Select this component when an I2C-configurable charger is required for single-cell applications. Compare against the BQ24250 and BQ24253 variants to determine if additional fault protection features or different input voltage ranges are necessary for the specific design constraints.

Battery Chargers Part Context

This part belongs to the BQ2425x family of highly integrated switch-mode chargers. It shares architectural similarities with the BQ24250 and BQ24253, differing primarily in specific feature sets such as fault protection mechanisms and input voltage tolerances. All variants utilize the same 30-DSBGA footprint.

Battery Chargers Replacement Considerations

Officially documented parameter-equivalent substitutes include the BQ24250YFFT and BQ24253YFFT. Verify functional differences regarding overcurrent and overtemperature protection configurations before substituting.
