BQ24165YFFT

Battery Chargers Overview

The BQ24165YFFT is a single-cell switchmode lithium-ion battery charger from Texas Instruments, housed in a 49-DSBGA (2.8x2.8) package. It supports an input voltage range of up to 10V and delivers a maximum programmable charging current of 2.5A. Designed for Li-Ion and Li-Polymer chemistries, it operates within a temperature range of -40°C to +85°C. The device integrates power path management and includes fault protection against overtemperature and short circuits.

Battery Chargers Feature Summary

• Integrates power path management for seamless system power transfer
• Supports dual-input configurations for flexible power sourcing
• Includes hardware-based overtemperature and short-circuit protection

Battery Chargers Applications

• Smartphones and mobile phones
• Tablets and portable media players
• Personal digital assistants (PDAs)
• MP3 players and audio devices

Battery Chargers Procurement Notes

Verify the specific suffix YFFT confirms the 49-DSBGA package variant when ordering. Ensure compatibility with the required input voltage profile not exceeding 10V. Confirm that the application design accounts for the thermal performance characteristics inherent to the small form factor surface-mount package during high-current operation.

Battery Chargers Selection Notes

Select this component for applications requiring a compact solution for single-cell lithium batteries. It is suitable where space constraints necessitate a DSBGA footprint. Consider its capability to manage system loads directly while charging the battery, reducing the need for additional power distribution components in the design.

Battery Chargers Part Context

This part belongs to the BQ24165 series of battery chargers. It shares functional similarities with other models in the family but is distinct due to its specific 49-DSBGA packaging. The series is designed for portable consumer electronics requiring efficient single-cell charging solutions.

Battery Chargers Replacement Considerations

The BQ24165RGET serves as a pin-compatible alternative offering the same electrical specifications in a VQFN-24 package. Designers may consider this replacement if a different footprint is preferred or available.
