10 A LiFePO4 charger with 28 V input ceiling
The BQ24620RVAT is a switch-mode battery charge controller from Texas Instruments, purpose-built for Lithium Iron Phosphate (LiFePO4) chemistries. Its 10 A max charge current and 28 V supply ceiling allow it to charge 1 to 7 series cells from a 24 V industrial bus or solar panel with headroom for line transients. The 26 V maximum battery pack voltage covers common 6S (19.2 V nominal) and 7S (22.4 V nominal) LiFePO4 stacks, making the part a direct fit for solar energy storage, UPS backup, and high-cycle-rate battery systems.
Fault protection and thermal design
Integrated fault protection covers overcurrent, overtemperature, overvoltage, and short-circuit conditions — reducing the external supervisory BOM for safety-certified designs. The 16-VQFN (3.5x3.5 mm) exposed-pad package requires a thermal via array under the paddle to the ground plane to keep the junction below 85°C at full 10 A charge current. The -40 to 85°C industrial temperature grade suits outdoor enclosures and unventilated battery compartments.
Active lifecycle — no design-in risk
New designs can proceed without a near-term migration plan. The base product number BQ24620 covers multiple package and tape options; the RVAT suffix identifies the 16-VQFN variant on Tape & Reel or Cut Tape, which is the standard procurement format for reflow assembly.
