BQ24161YFFR

Battery Chargers Overview

The BQ24161YFFR is a single-cell lithium-ion and lithium-polymer battery charger integrated circuit manufactured by Texas Instruments. It supports an input supply voltage range of 4 V to 10 V and delivers a maximum programmable charging current of 2.5 A. The device utilizes an I2C interface for configuration and monitoring. It is housed in a 24-VQFN (4x4 mm) package with exposed pad, suitable for surface-mount installation. The component operates within a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Integrates power path management for simultaneous system load sharing and battery charging
• Features I2C digital interface for precise control and status reporting
• Includes comprehensive safety protections against over-temperature and over-voltage conditions

Battery Chargers Applications

• Portable consumer electronics requiring single-cell Li-Ion/Polymer power solutions
• Handheld devices utilizing USB or wall adapter power inputs
• IoT modules and wearable technology with space-constrained PCB layouts

Battery Chargers Procurement Notes

Verify the specific suffix YFFR corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 24-VQFN footprint matches the design layout exactly. Ensure compatibility with the intended I2C bus addressing scheme before finalizing procurement orders.

Battery Chargers Selection Notes

Select this component when a compact solution with high current capability up to 2.5 A is needed for single-cell applications. The I2C interface allows for dynamic adjustment of charging parameters. Consider the thermal performance of the QFN package relative to the expected ambient operating conditions and board copper area.

Battery Chargers Part Context

This part belongs to the BQ2416x family of battery chargers from Texas Instruments. The family includes variants such as BQ24160, BQ24163, and BQ24168, which share similar functional architectures but may differ in pinout, package type, or specific feature sets like dual-input support.

Battery Chargers Replacement Considerations
