BQ24610RGER

Battery Chargers Overview

The BQ24610RGER is a standalone synchronous switch-mode Li-Ion or Li-Polymer battery charger controller designed for 1 to 6-cell battery packs. It features a 10A maximum charging current and supports input voltages from 5V to 28V. The device integrates system power path management, allowing seamless transition between adapter and battery sources. Key electrical parameters include a 600kHz switching frequency, ±0.5% voltage accuracy, and ±3% current accuracy. It operates within a junction temperature range of 0°C to 125°C and is housed in a 24-VQFN (4x4) package.

Battery Chargers Feature Summary

• Integrated system power path manager enables automatic source selection between the AC adapter and the battery to supply system loads.
• Synchronous buck architecture provides high conversion efficiency while minimizing thermal generation during operation.
• Comprehensive hardware protection mechanisms safeguard against input overvoltage, battery overvoltage, charging overcurrent, and thermal shutdown.

Battery Chargers Applications

• Portable computing devices such as laptops and tablets requiring multi-cell battery support
• Industrial equipment utilizing 1- to 6-cell lithium-ion or lithium-polymer battery configurations
• High-power consumer electronics needing efficient USB-C or adapter-based charging solutions

Battery Chargers Procurement Notes

Verify component authenticity through authorized Texas Instruments distributors or certified partners. Confirm the specific suffix matches the required package and tape-reel specifications. Check for moisture sensitivity level compliance and ensure storage conditions adhere to manufacturer guidelines before assembly. Validate that the procurement channel provides valid traceability documentation to prevent counterfeit risks.

Battery Chargers Selection Notes

Select this controller for applications requiring independent regulation of up to six series-connected cells. Ensure the external MOSFETs and inductor are rated for the 10A peak current and 28V input limits. Consider the thermal performance of the PCB layout given the 24-VQFN package size. Verify compatibility with the desired battery chemistry and system voltage requirements before finalizing the design.

Battery Chargers Part Context

This component belongs to the BQ2461x family of synchronous buck battery charger controllers. It serves as a core power management IC for portable electronics, offering a compact solution for high-efficiency charging. The RGER suffix specifically denotes the 24-VQFN package variant optimized for surface-mount assembly in space-constrained designs.

Battery Chargers Replacement Considerations

The BQ24610EVM is an evaluation board for this part, not a direct functional substitute. For equivalent functionality, consider other members of the BQ2461x family, such as the BQ24617, ensuring pinout and parameter compatibility.
