Product details

Single-cell Li-ion charger with I²C control

The Texas Instruments BQ24151YFFT is a single-cell Lithium Ion/Polymer linear charger IC with an I²C interface for programmable charge current, termination timer, and battery regulation voltage. It delivers a constant charge current up to 1.25 A max and regulates the battery pack voltage to 4.44 V max.

Package and footprint realities

Surface-mount assembly uses the 20-UFBGA, DSBGA package. The small footprint saves board area but makes manual rework difficult.

The BQ24151YFFT carries an Obsolete lifecycle status from Texas Instruments. Buyers holding a BOM line for this code will need to source through independent distribution or the surplus market.

Frequently asked questions

What is the difference between BQ24151 and BQ24151YFFT?

The BQ24151 is the base product number; the BQ24151YFFT is a specific variant in the 20-DSBGA package (YFF suffix indicates the DSBGA package code). The electrical specifications — I²C interface, 1.25 A charge current, 4.44 V battery regulation — are identical across the base part. The difference is purely the package form factor.
