• Handheld instrumentation

Battery Chargers Procurement Notes

Verify the specific suffix 'DGNR' corresponds to the MSOP-8 tape and reel packaging configuration. Confirm RoHS compliance status through the manufacturer's official documentation. Ensure the component matches the required operating temperature range of -40°C to +85°C for the intended application environment.

Battery Chargers Selection Notes

Select this component for applications requiring a compact solution for single-cell lithium batteries. It is suitable where input current limiting is necessary to protect upstream power sources. Consider the fixed 4.2V output if adjustable voltage settings are not required by the design.

Battery Chargers Part Context

This part belongs to the bqTINY family of charge management ICs designed for space-constrained portable devices. It simplifies battery charging by combining linear charger functionality with power path management in a small footprint, reducing overall bill of materials complexity.

Battery Chargers Replacement Considerations

Check for BQ24202DGNG4 as a potential variant. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement supports the same MSOP-8 package and thermal requirements.
