Battery Management Procurement Notes

Verify the specific suffix YFFT corresponds to the 49-pin DSBGA package and the -40°C to +85°C operating temperature range. Confirm that the I2C interface and over-temperature protection features align with your system requirements. Ensure compatibility with single-cell lithium-ion battery architectures before procurement.

Battery Management Selection Notes

Select this component when designing for single-cell lithium-ion systems requiring a compact footprint. The 49-pin DSBGA package suits space-constrained designs. Verify that the 0.8-A output current meets the load demands of the memory voltage rail. Ensure the host controller supports the required I2C communication protocol for configuration.

Battery Management Part Context

This part belongs to Texas Instruments' family of power management ICs tailored for portable electronics. It integrates multiple functions into a small form factor, reducing board space compared to discrete solutions. The YFFT designation specifically identifies the 49-pin DSBGA variant suitable for surface-mount assembly.

Battery Management Replacement Considerations

Consult official substitution guides for compatible PMICs with similar pin counts and I2C interfaces. Verify thermal performance and current capabilities match the original design constraints before replacing.
