• Supports SMBus/I2C interface for digital control and monitoring
• Configurable for 1 to 4 series lithium-ion cells
• Integrated thermal regulation and fault protection

Battery Chargers Applications

• Portable medical devices
• Industrial equipment batteries
• Uninterruptible power supplies (UPS)

Battery Chargers Procurement Notes

Verify the exact suffix against the manufacturer's official datasheet to confirm package type and temperature grade. Ensure compatibility with existing I2C addressing schemes in the target design. Confirm availability status as product lifecycle stages may affect long-term sourcing. Cross-reference pinouts with previous revisions if migrating from older components.

Battery Chargers Selection Notes

Select this component when designing systems requiring precise digital control over multi-cell lithium-ion battery charging profiles. It is suitable for applications needing flexible input voltage ranges up to 24 V. Consider its I2C interface for systems demanding detailed telemetry and configuration adjustments via software rather than analog resistors.

Battery Chargers Part Context

This part belongs to Texas Instruments' BQ247xx family of high-performance battery chargers. These controllers are engineered for complex battery management systems that require advanced diagnostics and communication protocols. The RGRR suffix typically denotes a specific tape-and-reel packaging format intended for automated surface-mount assembly processes.

Battery Chargers Replacement Considerations

Check for direct cross-references within the BQ247xx family such as the BQ24725 or BQ24727, ensuring pinout and feature parity. Verify that any substitute maintains the same I2C addressability and voltage handling capabilities.
