Device Overview
BQ24610RGER is the large-reel VQFN-24 orderable of Texas Instruments’ standalone synchronous buck battery-charge controller. It drives external high-side and low-side N-channel MOSFETs, allowing the charger power stage to be scaled beyond what an integrated-FET charger can dissipate.

Engineering Selection Notes
The 10 A figure belongs to the complete external power-stage design, not to current carried through the controller IC. MOSFET RDS(on), inductor saturation, sense-resistor dissipation, switching loss, cooling and PCB copper determine whether a 10 A charge target is practical.
BQ24610 regulates adapter current separately from battery charge current. Its dynamic power-management loop can reduce charging current when the system load approaches the programmed adapter-current limit, which helps keep the adapter within a controlled input-current budget.
The 5 V to 28 V figure is the controller VCC operating range. Battery-stack voltage, adapter headroom and synchronous-buck duty-cycle limits still need to be checked for the selected 1- to 6-cell configuration.
