Product details

Single-cell Li-Ion charger with I²C control

The BQ24271YFFR is a Texas Instruments single-cell Lithium Ion battery charger IC that uses an I²C interface to set the charge current up to a maximum of 1.5A, making it suitable for portable devices where the charge profile must be adjusted by the system host. Rated for a battery pack voltage of 3.7V and a maximum supply voltage of 6V, the device integrates fault protection for over-temperature, over-voltage, and short-circuit conditions, reducing external component count in the charging path.

Package and thermal environment

Housed in a 49-ball DSBGA (2.8x2.8 mm) package, the BQ24271YFFR is a surface-mount device supplied on Tape & Reel.

Frequently asked questions

What is the maximum charge current for BQ24271YFFR?

The maximum programmable charge current is 1.5A, set via the I²C interface. The charging method is constant-current programmable, allowing the host controller to adjust the charge rate dynamically.

What fault protection does BQ24271YFFR include?

The device integrates over-temperature, over-voltage, and short-circuit protection, covering the most common fault conditions in single-cell Li-Ion charging applications.
