BQ24113ARHLRG4

Battery Chargers Overview

The BQ24113ARHLRG4 is a synchronous switch-mode lithium-ion and lithium-polymer battery charger from the bqSWITCHER series. It supports 1 to 2-cell battery packs with a maximum charge current of 2A and a supply voltage up to 16V. The device features programmable charge current and timer, along with over-temperature and over-voltage fault protection. It operates within a temperature range of -40°C to +85°C and is housed in a 20-VQFN (3.5x4.5mm) package.

Battery Chargers Feature Summary

• Synchronous switching architecture for high efficiency
• Programmable charge current and timer settings
• Integrated over-temperature and over-voltage protection

Battery Chargers Applications

• Portable electronic devices requiring Li-Ion/Polymer charging
• Single or dual-cell battery management systems
• Power path management applications

Battery Chargers Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official datasheet to confirm RoHS compliance status and any functional differences compared to the standard BQ24113 variant. Ensure the ordering part number matches the exact package and tape/reel specifications required for your assembly process.

Battery Chargers Selection Notes

Select this component when designing systems that require a compact, high-efficiency solution for 1 to 2-cell lithium batteries. It is suitable for applications needing adjustable charge currents up to 2A and integrated power path management within a small 20-pin QFN footprint.

Battery Chargers Part Context

This part belongs to Texas Instruments' bqSWITCHER family of standalone switching battery chargers. It shares architectural similarities with other members like the BQ24100 and BQ24115 but is specifically optimized for 1-2 cell configurations with a 2A current limit.

Battery Chargers Replacement Considerations

Direct substitutes include BQ24113ARHLR. Verify pinout and electrical parameters against the official datasheet before substitution.
