Technical Details & Description

The I²C interface lets the system host set charge current, termination threshold, and safety timer without external resistors or jumper straps. That saves two or three passives per board and makes the charge profile adjustable in firmware — useful when the same PCB must support different cell capacities across product variants. The base product number BQ24180 covers the family; the YFFT suffix identifies the 25-DSBGA package and the Tape & Reel / Cut Tape shipping options.

1.5A charge current — sizing the rail

The 1.5A maximum charge current is the peak the charger can deliver to a single cell. The 16V maximum supply voltage gives headroom for 5V USB input or a 12V wall adapter.

Frequently asked questions

What is the difference between BQ24180YFFT and BQ24180?

BQ24180 is the base product number for the family. The YFFT suffix specifically identifies the 25-DSBGA package variant in Tape & Reel or Cut Tape. The base part number without the suffix covers all package options; the electrical specifications (single-cell Li-Ion/Polymer charger, I²C interface, 1.5A max charge current, 4.44V max battery voltage) are common across the family.

Can BQ24180YFFT charge a 4.2V single cell battery?

Yes. The maximum battery regulation voltage is 4.44V, which covers the standard 4.2V Li-Ion/Polymer termination voltage. The I²C interface allows programming the regulation voltage to 4.2V or other levels within the 4.44V maximum.

How to program the charge current for BQ24180YFFT via I²C?

The charge current is set through the I²C interface by writing to the charger's control registers. The maximum programmable current is 1.5A. The exact register map and command sequence are documented in the device datasheet; the base product number BQ24180 covers the family documentation.
