BQ25980YFFR

Battery Chargers Overview

The BQ25980YFFR is an I2C-controlled, dual-cell switched-capacitor parallel battery charger with integrated protection and a dual-input selector. It supports lithium-ion, lithium-polymer, and lithium iron phosphate chemistries. The device delivers up to 8A of charge current per cell for a total of 16A in parallel mode. It operates from a supply voltage range of 3.2V to 12V and provides an output voltage range of 3V to 6V. Packaged in a DSBGA-56 footprint, it functions within a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Dual-input selector enables flexible power source management
• Integrated protection circuitry ensures safe operation
• Supports parallel charging configuration for high-current applications

Battery Chargers Applications

• Portable computing devices requiring rapid charging
• Industrial equipment with dual-power inputs
• High-performance mobile communication hardware

Battery Chargers Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package and tape-and-reel specifications. Ensure compatibility with system I2C addressing requirements before integration. Confirm that the dual-input selector aligns with the target power architecture. Validate thermal performance under maximum load conditions using official application notes.

Battery Chargers Selection Notes

Select this component for designs requiring high-current parallel charging of two series-connected cells. It is suitable where input flexibility and integrated protection are critical. Compare against single-cell alternatives if only one cell is present. Ensure the PCB layout accommodates the DSBGA-56 package dimensions and thermal requirements specified in the mechanical outline drawing.

Battery Chargers Part Context

This part belongs to the BQ25980 family of switched-capacitor battery chargers. It is designed for applications needing efficient, high-current charging without external inductors. The family includes variants with different suffixes indicating packaging or revision differences. It falls under the PMIC category for power management ICs.

Battery Chargers Replacement Considerations

Check for BQ25980YFFT as a potential alternative package variant. Verify electrical equivalence with BQ25970YFFR if single-cell operation suffices. Confirm pinout compatibility before substituting any other TI battery management IC.
