Battery Chargers Procurement Notes

Verify the specific suffix YFFT corresponds to the 20-DSBGA package variant when sourcing. Confirm RoHS3 compliance status as required by project specifications. Check for obsolescence notices or PCN updates regarding this part number before finalizing procurement plans. Ensure compatibility with existing I2C bus configurations in the target system design.

Battery Chargers Selection Notes

Select this component for applications requiring a compact solution for single-cell Li-Ion or Li-Po batteries. The I2C interface allows for dynamic adjustment of charging parameters without external resistors. Consider the 20-DSBGA package size constraints and thermal dissipation requirements. Verify that the input voltage source does not exceed the maximum rated supply voltage of 6V during operation.

Battery Chargers Part Context

This device belongs to the BQ2415x family of battery chargers from Texas Instruments. It shares functional similarities with the BQ24150 and BQ24152 models but offers specific pinout and feature variations. The family is designed for portable applications where space efficiency and programmability are critical. It serves as a dedicated power management solution for systems powered by single-cell rechargeable batteries.

Battery Chargers Replacement Considerations
