BQ24250YFFR

Battery Chargers Overview

The BQ24250YFFR is a single-cell lithium-ion battery charger from Texas Instruments, operating within a supply voltage range of 4.35 V to 10.5 V. It delivers a programmable output current up to 2 A and supports an adjustable output voltage. The device utilizes an I2C interface for configuration and monitoring. It is housed in a compact 30-DSBGA package designed for surface-mount installation. The component operates reliably across a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Integrates a standalone switch-mode buck converter architecture for efficient power conversion.
• Features an I2C digital interface enabling precise control over charging parameters and system status.
• Includes comprehensive protection mechanisms against over-temperature, over-voltage, and input fault conditions.

Battery Chargers Applications

• Portable consumer electronics requiring single-cell lithium-ion power sources
• Handheld devices utilizing I2C-configurable charging management
• Compact embedded systems with strict space constraints

Battery Chargers Procurement Notes

Verify the specific suffix YFFR corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the 30-DSBGA footprint matches your PCB design guidelines. Ensure compatibility with your I2C bus voltage levels and check for any recent production change notices affecting pinout or electrical characteristics before finalizing procurement.

Battery Chargers Selection Notes

Select this component when a single-input, single-cell solution with digital control is required. It is suitable for designs needing up to 2 A charging current within a 4.35 V to 10.5 V input window. Consider the DSBGA package size relative to available board real estate. Verify thermal performance requirements given the small form factor and potential heat dissipation needs during high-current operation.

Battery Chargers Part Context

This part belongs to the BQ24250 family of single-cell battery chargers. It shares architectural similarities with other members like the BQ24250CYFFR and BQ24253 series, differing primarily in package type and specific electrical tolerances. The family targets portable applications requiring efficient, digitally controlled charging solutions from Texas Instruments.

Battery Chargers Replacement Considerations

The BQ24250CYFFT is documented as a parameter-equivalent alternative. Verify package compatibility between DSBGA variants and confirm I2C address settings match your system design before substitution.
