BQ51050BRHLT

Power Management - Specialized Overview

The BQ51050BRHLT is a secondary-side integrated circuit for wireless power transfer, compliant with WPC 1.1 standards. It functions as a direct lithium-ion battery charger receiver. The device supports an output voltage of 4.2 V and delivers up to 1.5 A output current, enabling 5 W output power. It operates on a supply voltage range of 4 V to 10 V with a maximum operating current of 1.5 A. The component is housed in a VQFN-20 package and is rated for operation between 0°C and +125°C.

Power Management - Specialized Feature Summary

• Integrates direct charging capability for lithium-ion batteries within the receiver assembly
• Complies with Wireless Power Consortium (WPC) 1.1 specifications for interoperability
• Supports high-power delivery up to 5 W through optimized secondary-side management

Power Management - Specialized Applications

• Secondary-side wireless power receivers
• Direct lithium-ion battery charging systems
• Portable electronic devices requiring wireless power input

Power Management - Specialized Procurement Notes

Verify the specific suffix BRHLT against the manufacturer's official datasheet to confirm the VQFN-20 package and reel packaging configuration. Ensure compatibility with the intended WPC 1.1 transmitter infrastructure. Confirm that the 0°C to +125°C operating temperature range meets the environmental requirements of the final application design.

Power Management - Specialized Selection Notes

Select this component when designing a secondary-side receiver that requires direct integration with a lithium-ion cell without intermediate regulation stages. The 4 V to 10 V supply range accommodates various rectified AC voltages from the primary coil. The VQFN-20 package offers a compact footprint suitable for space-constrained portable electronics.

Power Management - Specialized Part Context

This part belongs to the BQ51050B series of wireless charging ICs manufactured by Texas Instruments. The series includes variants such as BQ51050BYFPR, which utilizes a DSBGA-28 package. These components are categorized under wireless charging receivers designed for efficient power transfer and battery management in consumer electronics.

Power Management - Specialized Replacement Considerations

The BQ51050BYFPR serves as a package variant within the same functional family, utilizing a DSBGA-28 footprint instead of VQFN-20. Verify pinout compatibility and thermal performance differences before substitution.
