Product details

It communicates over an I²C bus, so the host microcontroller sets the charge voltage, current, and termination parameters — no external resistors needed for the charge profile. The part integrates over-temperature and over-voltage fault protection, which saves board space by eliminating external supervisor ICs on the battery rail.

Supply rail and thermal design

The maximum supply voltage is 16 V, which covers USB VBUS (5 V) and common 12 V wall adapters without an external pre-regulator. The battery regulation voltage tops out at 4.44 V — that is the standard termination for a single-cell Li-ion at 4.2 V nominal plus a small top-off window. Operating temperature spans -30°C to 85°C, so the part works in portable consumer gear, handheld instruments, and indoor industrial equipment.

Package and footprint for reflow

The BQ24180YFFR comes in a 25-bump DSBGA package (0.5 mm pitch, 25-UFBGA). The supplier device package is 25-DSBGA. Cut Tape quantities are also available for prototype builds.

Frequently asked questions

What is the difference between BQ24180YFFR and BQ24180YFFT?

The BQ24180YFFR and BQ24180YFFT share the same base product number BQ24180, so they are functionally identical — same I²C interface, same 1.5 A charge current, same 25-DSBGA package. The suffix difference typically indicates packaging or reel quantity variant. Confirm the specific suffix with the datasheet or your TI sales contact.

Does BQ24180YFFR support USB charging?

Yes. The 16 V maximum supply voltage covers USB VBUS at 5 V, and the I²C interface allows the host to negotiate charge parameters per the USB battery charging specification. The part is designed for single-cell Li-ion/polymer charging from USB or wall-adapter inputs.
