BQ24103ARHLR

Battery Chargers Overview

The BQ24103ARHLR is a standalone synchronous switch-mode Li-Ion charger manufactured by Texas Instruments. It integrates a 2A FET and operates within an input voltage range of 4.35 V to 16 V, with an absolute maximum rating of 20 V. The device supports single-cell lithium-ion and lithium-polymer batteries, delivering a maximum charge current of 2 A. It utilizes pulse width modulation control in a voltage-mode architecture. The component is housed in a 20-pin HVQCCN (VQFN) package measuring 4.5 mm by 3.5 mm with a height of 0.9 mm. It functions reliably across a temperature range of -40 °C to +85 °C.

Battery Chargers Feature Summary

• Integrates internal synchronous power FETs for high-efficiency charging
• Supports programmable charge current and termination timer via external components
• Includes thermal regulation and input current limiting features

Battery Chargers Applications

• Portable consumer electronics requiring compact battery charging solutions
• Single-cell lithium-ion or lithium-polymer battery management systems
• Industrial devices operating in extended temperature environments

Battery Chargers Procurement Notes

Verify the specific suffix ARHLR against official datasheets to confirm pinout and package dimensions. Ensure compatibility with the intended PCB footprint, as the 20-VQFN package requires precise soldering. Confirm RoHS compliance status through manufacturer documentation before integration into regulated products.

Battery Chargers Selection Notes

Select this component for applications requiring a standalone switching charger without external MOSFETs. It is suitable for designs needing up to 2 A charge current from standard USB or wall adapter sources. Consider the thermal performance of the VQFN package when designing heat dissipation paths for continuous high-current operation.

Battery Chargers Part Context

This part belongs to the bqSWITCHER family of battery chargers from Texas Instruments. It shares architectural similarities with other models like the BQ24100 and BQ24113 but is optimized for single-cell applications. The series focuses on providing integrated power solutions for portable devices while minimizing external component count.

Battery Chargers Replacement Considerations

Check for direct substitutes such as BQ24100 or BQ24113 if pin-to-pin compatibility is required. Verify that alternative parts support the same 2 A current capability and input voltage range. Ensure any replacement maintains the 20-VQFN package form factor for existing board layouts.
