BQ24188YFFR

Battery Chargers Overview

The BQ24188YFFR is a fully integrated single-cell lithium-ion battery charger IC manufactured by Texas Instruments. It operates within an input voltage range of 4 V to 16 V and delivers a programmable output current up to 3 A. The device utilizes a DSBGA-36 package for compact surface-mount installation. It supports standard charging profiles including pre-conditioning, constant current, and constant voltage phases with termination control. The component functions across an extended temperature range from -40°C to +85°C, ensuring reliable performance in various portable electronic applications.

Battery Chargers Feature Summary

• Fully integrated switch-mode architecture combining power path management and charge regulation
• I2C interface for comprehensive configuration and monitoring of charging parameters
• Programmable input current limit and system load prioritization for power management

Battery Chargers Applications

• Portable computing devices such as tablets and ultrabooks
• Smartphones and mobile communication handsets
• Personal digital assistants (PDAs) and handheld gaming consoles
• Medical equipment requiring single-cell lithium-ion power sources

Battery Chargers Procurement Notes

Verify the specific suffix YFFR corresponds to the DSBGA-36 package and reel packaging configuration. Confirm that the I2C address and default register settings align with your system design requirements. Ensure compatibility with the intended lithium-ion or lithium-polymer cell chemistry before integration into the final product assembly line.

Battery Chargers Selection Notes

Select this component when a compact solution is required for single-cell charging with high efficiency. The integrated power path allows simultaneous operation while charging, reducing external component count. Consider the thermal performance of the DSBGA-36 package relative to the expected continuous discharge current and ambient operating conditions during selection.

Battery Chargers Part Context

This part belongs to the BQ2418x family of single-cell Li-Ion chargers. It shares architectural similarities with the BQ24180 but offers enhanced current capabilities and refined power path management features. The series is designed for consumer electronics where space constraints and charging speed are critical design factors.

Battery Chargers Replacement Considerations

The BQ24180YFFR is a related variant within the same family. Verify pin-to-pin compatibility and software register mapping differences before substitution. Ensure that the lower maximum output current of alternative parts meets the system's charging time requirements.
