BQ24185YFFR

Battery Chargers Overview

The BQ24185YFFR is a fully integrated switch-mode single-cell lithium-ion battery charger manufactured by Texas Instruments. It operates with an input voltage range of 4 V to 16 V and delivers up to 3 A of charge current. The device supports 1.6 MHz synchronous switching for high efficiency and includes full USB compliance features. It integrates a power path management system that optimizes system power distribution. The component is housed in a DSBGA-25 package and functions within a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Integrates a synchronous buck converter with a 1.6 MHz switching frequency for compact design and high efficiency.
• Provides full USB On-The-Go (OTG) accessory power connection capabilities for host mode operation.
• Features intelligent power path management to balance system load and battery charging simultaneously.
• Includes comprehensive safety protections such as thermal regulation and input current limiting.

Battery Chargers Applications

• Smartphones and mobile phones requiring USB OTG functionality
• Tablets and portable media players
• Digital cameras and camcorders
• Portable medical devices

Battery Chargers Procurement Notes

Verify the specific suffix YFFR corresponds to the DSBGA-25 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supply chain source provides valid traceability certificates. Cross-reference the latest datasheet revision to confirm pinout compatibility with existing PCB layouts. Validate that the procurement channel is authorized to prevent counterfeit components.

Battery Chargers Selection Notes

Select this component when a compact, high-efficiency solution for single-cell Li-Ion or Li-Polymer batteries is required. It is suitable for applications needing USB OTG host capabilities alongside charging. Consider the 1.6 MHz switching frequency for minimizing external passive component size. Evaluate the 3 A output current capability against peak system power demands. Ensure the input voltage range aligns with the available power source specifications.

Battery Chargers Part Context

This part belongs to the BQ2418x family of fully integrated switch-mode chargers from Texas Instruments. These devices are designed for portable electronics requiring small form factors and high performance. The family emphasizes USB compliance and power path management. The BQ24185 variant specifically adds accessory power connection features compared to standard models. It targets modern mobile devices where space and efficiency are critical constraints.

Battery Chargers Replacement Considerations

The BQ24180YFFR is a related model but lacks the USB OTG accessory power feature. Verify if the host mode requirement necessitates the BQ24185 over the BQ24180. Check pin-to-pin compatibility if substituting within the same package type. Review datasheets for differences in switching frequency and protection thresholds.
