BQ24168YFFT

Battery Chargers Overview

The BQ24168YFFT is a single-cell switched-mode Li-Ion battery charger manufactured by Texas Instruments. It supports dual inputs and provides up to 2.5A of charge current with integrated power path management. The device features an I2C interface for configuration and monitoring. It operates within a supply voltage range of 4V to 10V and includes protection features such as OVP, UVLO, and thermistor-based temperature monitoring. The component is housed in a DSBGA-49 package.

Battery Chargers Feature Summary

• Dual-input capability supporting multiple power sources
• Integrated power path management for system load prioritization
• I2C interface for programmable control and status monitoring
• Thermistor pin for JEITA-compliant battery temperature monitoring

Battery Chargers Applications

• Portable consumer electronics requiring single-cell Li-Ion charging
• Mobile devices utilizing dual-power source architectures
• IoT devices with strict power path management requirements
• Battery-powered equipment needing I2C-configurable charging profiles

Battery Chargers Procurement Notes

Verify the specific suffix YFFT corresponds to the DSBGA-49 tape-and-reel packaging configuration. Confirm that the I2C address and default register settings align with the target system design. Ensure thermal dissipation requirements are met given the high-current switching operation in the small form factor package.

Battery Chargers Selection Notes

Select this component when dual-input flexibility and integrated power path management are required for single-cell applications. The I2C interface allows for precise customization of charging parameters compared to fixed-function chargers. Consider the DSBGA-49 package size constraints and thermal performance relative to the expected ambient operating conditions.

Battery Chargers Part Context

This part belongs to the BQ2416xx family of dual-input, single-cell switchmode battery chargers. It shares functional similarities with parts like the BQ24160 and BQ24165 but offers specific integration levels and interface options. The family is designed for portable applications requiring efficient charging and robust power path management.

Battery Chargers Replacement Considerations

Publicly confirmed substitute part numbers include BQ24160, BQ24161, BQ24163, and BQ24165. Verify pinout compatibility and I2C register mapping before substitution.
