BQ24158YFFT

Battery Chargers Overview

The BQ24158YFFT is a fully integrated switch-mode single-cell lithium-ion battery charger manufactured by Texas Instruments. It supports full USB compliance and USB-OTG functionality, allowing the device to act as a host. The component operates within an input voltage range of 4.35V to 5.5V and delivers a programmable charge current up to 1.5A. It features a compact 20-pin DSBGA package with dimensions of 2.63mm x 2.46mm. The device includes thermal regulation and input current limiting to optimize power source usage.

Battery Chargers Feature Summary

• Fully integrated switch-mode architecture supporting single-cell Li-Ion and Li-Polymer batteries
• Full USB compliance with USB-OTG support for host functionality
• Programmable charge current and termination voltage via I2C interface
• Integrated thermal regulation and dynamic power management

Battery Chargers Applications

• Smartphones and mobile phones
• Tablets and portable media players
• GPS navigation devices
• Digital cameras and camcorders

Battery Chargers Procurement Notes

Verify the specific suffix YFFT against the official datasheet to confirm the 20-DSBGA package type and tape-and-reel packaging configuration. Confirm that the intended application requires USB-OTG host capabilities, as this distinguishes the BQ24158 from standard charger variants. Ensure design compatibility with the I2C control interface for current and voltage programming.

Battery Chargers Selection Notes

Select this component when USB-OTG host support is required alongside charging functions. It is suitable for applications needing precise input current limiting from USB ports. Compare against the BQ24150 or BQ24155 if OTG features are unnecessary. Verify that the 20-DSBGA footprint fits the PCB layout constraints.

Battery Chargers Part Context

The BQ24158 belongs to Texas Instruments' family of fully integrated switch-mode chargers designed for portable electronics. It shares architectural similarities with the BQ24150 and BQ24153 but adds specific USB-OTG support. This series targets high-volume consumer electronics requiring efficient power management in minimal space.

Battery Chargers Replacement Considerations

Publicly confirmed substitutes include the BQ24150YFFT and BQ24153YFFT. Note that these alternatives may lack USB-OTG host support. Verify pinout compatibility and software register mapping before substitution.
