BQ25010RHLR

Battery Chargers Overview

The BQ25010RHLR is a single-chip charger and DC/DC converter IC designed for Bluetooth headsets. It integrates a synchronous step-down DC/DC converter with a lithium-ion/polymer battery charger. The device supports an input voltage range of 4.3 V to 16 V and delivers up to 1 A of output current. It features a fixed 4.2 V charging voltage and operates within a temperature range of -40°C to +85°C. The component is housed in a VQFN-20 package measuring 3.5x4.5 mm.

Battery Chargers Feature Summary

• Integrates a synchronous step-down DC/DC converter with a Li-Ion/Polymer battery charger
• Supports direct connection to USB or wall adapter power sources
• Includes thermal regulation and automatic charge termination

Battery Chargers Applications

• Bluetooth headset systems
• Portable audio devices
• Single-cell lithium-ion powered gadgets

Battery Chargers Procurement Notes

Verify the specific suffix RHLR against the official Texas Instruments datasheet to confirm the VQFN-20 package and tape-and-reel configuration. Ensure compatibility with the target application's input voltage requirements, as the device specifies a minimum operating voltage of 4.3 V. Confirm that the 1 A output current meets the system load demands.

Battery Chargers Selection Notes

Select this component for applications requiring a compact solution combining power conversion and battery management. It is suitable for low-power portable electronics where space is limited. Consider the fixed 4.2 V output if using standard single-cell lithium batteries. Evaluate the thermal performance under maximum load conditions given the small package size.

Battery Chargers Part Context

This part belongs to the BQ2501x series of integrated chargers and converters from Texas Instruments. It is specifically optimized for ultra-low power applications such as wireless audio peripherals. The design simplifies bill of materials by combining two functions into one chip, reducing board space compared to discrete solutions.

Battery Chargers Replacement Considerations

Check for updated revisions within the BQ2501x family. Verify pin-to-pin compatibility with alternative TI models like the BQ25017 if higher current ratings are needed, though functional differences exist.
