Power Management - Specialized Procurement Notes

Verify the specific suffix BYFPR to confirm the DSBGA-28 package type and reel packaging configuration. Ensure compatibility with WPC 1.1 compliant transmitters. Confirm thermal management requirements for operation up to +125°C. Validate that the application design supports the 4 V to 10 V input voltage range. Check datasheet for moisture sensitivity handling instructions.

Power Management - Specialized Selection Notes

Select this component when a compact DSBGA-28 footprint is required for secondary-side wireless charging applications. It is suitable for designs needing direct lithium-ion battery integration with a 4.2 V output. Consider the 1.5 A current limit and 5 W power capability against system demands. Ensure the operating environment stays within the 0°C to +125°C temperature range.

Power Management - Specialized Part Context

This part belongs to the BQ51050B series of wireless charging ICs from Texas Instruments. It is specifically configured for secondary-side reception and direct battery charging. The BYFPR suffix denotes the specific tape-and-reel packaging and DSBGA-28 package variant within this product family.

Power Management - Specialized Replacement Considerations

The BQ51050BRHLT offers similar functionality but uses a VQFN-20 package instead of DSBGA-28. Verify pinout compatibility and thermal performance differences before substitution.
