Product details

2.5A programmable charge current with I²C control

The BQ24160YFFR is a single-cell Li-Ion/Polymer battery charger from Texas Instruments, controlled over an I²C interface. It delivers a programmable constant charge current up to 2.5A max, with the charge voltage set for a 3.7V battery pack. Fault protection covers over-temperature and over-voltage conditions, making it suitable for portable devices that need a host-controlled charging profile.

Where it fits in the charging cycle

This part sits between a 10V max supply rail and a single Li-Ion or Li-Polymer cell. The I²C interface lets a system MCU set the charge current dynamically — useful for thermal management or USB input current limiting.

Package and board integration

Housed in a 49-DSBGA (2.8x2.8 mm) package with surface-mount termination. The 0.50 mm ball pitch and small footprint demand a controlled-impedance PCB stack and careful thermal via placement under the package. The supplier device package is 49-DSBGA (2.8x2.8).

Frequently asked questions

What is the maximum charge current for BQ24160YFFR?

The maximum charge current is 2.5A, programmable via the I²C interface. The charge current is constant and programmable, not fixed.

What is the difference between BQ24160YFFR and BQ24160YFFT?

The BQ24160YFFR and BQ24160YFFT share the same base product number BQ24160 and the same 49-DSBGA package. The difference is in the shipping packaging — the YFFR suffix typically indicates Tape & Reel (TR) while the YFFT suffix indicates a different reel or tube quantity. Both are active and functionally identical.
