• Includes input dynamic power management to prevent errors from misconfigured USB power sources
• Designed to meet USB-IF surge current specifications through precise input current limiting

Battery Chargers Applications

• Portable consumer electronics requiring space-constrained battery charging solutions
• USB-powered devices needing compliant surge current handling
• Systems utilizing non-regulated AC adapters or USB power supplies
• Single-cell lithium-ion or lithium-polymer battery management in compact form factors

Battery Chargers Procurement Notes

Verify the specific suffix 'RGTR' corresponds to the tape-and-reel packaging configuration as indicated in official documentation. Confirm that the 16-VQFN package dimensions match your PCB footprint requirements. Ensure compatibility with the specified 4.35 V to 6.4 V input voltage range for your power source design. Check for any lead-free or RoHS compliance certifications required by your manufacturing standards.

Battery Chargers Selection Notes

Select this component when a single-cell Li-Ion charger with integrated power-path management is required. It is suitable for designs where input current limiting must comply with USB-IF surge specifications. Consider this part for applications limited to a 1.5 A charge current and a 4.4 V output voltage setting. It is appropriate for systems operating within the -40 °C to +85 °C temperature range using a 16-VQFN package.

Battery Chargers Part Context

This device belongs to the BQ2407x family of Li-Ion battery chargers from Texas Instruments. It shares functional similarities with other members like the BQ24072 and BQ24073 but is distinguished by its specific 4.4 V output voltage setting and 1.5 A current capability. The family is designed for portable applications requiring efficient charging and power management in small footprints.
