Product details

SMBus-controlled Li-Ion charger for 2-3 cell notebooks

The BQ24715RGRR is a SMBus host-controlled battery charger IC from Texas Instruments, designed for 2-3 series Li-Ion cells with a maximum supply voltage of 24V. The SMBus interface lets the system microcontroller set charge voltage and current programmatically — no external resistor dividers for the charge profile, but the host firmware must implement the SMBus protocol to drive the charger.

Cell count and input supply limits

Rated for 2 to 3 cells with a 24V supply maximum. A 4-cell Li-Ion pack (nominal ~14.8V, full charge ~16.8V) stays within the 24V input ceiling, but the BQ24715RGRR is not configured for 4-cell chemistry — the cell-count register and charge algorithm expect 2-3 series. For a 4-cell design, look at the BQ24725RGRR sibling, which supports 2-4 cells and shares the same 20-VQFN footprint.

Frequently asked questions

What is the difference between BQ24715RGRR and BQ24725RGRR?

The BQ24725RGRR supports 2-4 series Li-Ion cells, while the BQ24715RGRR is limited to 2-3 cells. Both share the same 20-VQFN (3.5x3.5) package and SMBus interface. For a 4-cell design, the BQ24725RGRR is the direct alternative.

Does BQ24715RGRR support fast charging?

The BQ24715RGRR uses an SMBus host-controlled charge algorithm; fast charging is supported if the host firmware programs the appropriate charge current and voltage via the SMBus interface. The maximum charge current is set by the host, not a fixed hardware limit.
