Product details

It delivers up to 3A charge current to a 4.2V battery pack, with built-in over-temperature and over-voltage fault protection.

3A charge current and I²C control — what drives the BOM fit

The I²C interface allows the host microcontroller to program the charge current in real time, enabling adaptive charging profiles based on battery temperature or input power budget. Supply voltage maximum is 6V, so the input rail must be regulated — a 5V USB bus is fine, but a raw 12V adapter would need a front-end buck converter.

Engineers designing new products should evaluate a current-production single-cell Li-Ion charger from TI's portfolio, such as a BQ256xx or BQ258xx series device, which offer similar I²C programmability and higher integration.

Frequently asked questions

Is the BQ24262YFFR obsolete and what is the replacement?

Yes, the BQ24262YFFR is obsolete per Texas Instruments' product status. No official replacement part number is listed in the available lifecycle data. For new designs, consider a current-production TI charger such as a BQ256xx or BQ258xx series device with I²C control.
