Battery Chargers Procurement Notes
Verify the exact suffix RHDR against official Texas Instruments documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with required operating temperatures and input voltage ranges before integration. Cross-reference part markings with datasheet guidelines to authenticate components during procurement.
Battery Chargers Selection Notes
Select this component when multi-chemistry flexibility is required alongside compact VQFN packaging. Consider the 28V input limit and 9.4mA LDO output capability for system design. Evaluate thermal performance within the specified -40°C to 125°C range for environmental suitability.
Battery Chargers Part Context
This part belongs to the BQ2470x family of battery chargers from Texas Instruments. It shares architectural similarities with variants like BQ24702 and BQ24703PW, differing primarily in package type and specific pinout configurations. The family targets applications requiring robust battery management with minimal external component count.
Battery Chargers Replacement Considerations
BQ24703PWG4 offers equivalent functionality in a TSSOP-24 package. BQ24703PW provides similar features in a standard TSSOP form factor. Verify pin-to-pin compatibility and thermal characteristics when substituting.
