Product details

Multi-chemistry charger with 28 V input ceiling

The Texas Instruments BQ24650RVAT is a multi-chemistry battery charger controller that handles Li-Ion, LiFePO4, and lead-acid chemistries from a single design. Its 28 V maximum supply voltage suits it for solar-panel-fed charge controllers, industrial battery backup systems, and portable equipment where the input rail can range from a regulated adapter to an unregulated panel output.

Programmable charge current and fault protection

Charge current is programmable via an external sense resistor, letting the designer match the charge rate to the battery capacity without swapping the IC. On-chip over-temperature and over-voltage protection guard against fault conditions during unattended charging — relevant for remote or outdoor installations where a runaway charge event could damage the battery or the load.

Industrial temperature grade and 16-VQFN package

The 16-VFQFN with exposed pad (3.5 mm × 3.5 mm body) provides a low thermal resistance path to the PCB copper plane — essential for dissipating the heat from the internal FETs during high-current charge cycles.

Frequently asked questions

Can BQ24650RVAT charge LiFePO4 batteries?

Yes. The BQ24650RVAT is a multi-chemistry charger that supports LiFePO4 (lithium iron phosphate) cells. The charge voltage and current are set by external resistor dividers and a sense resistor, so the designer configures the termination voltage for the LiFePO4 chemistry (typically 3.6 V per cell) rather than the 4.2 V used for standard Li-Ion.

Is BQ24650RVAT a replacement for BQ24650RVAR?

The BQ24650RVAT and BQ24650RVAR share the same base product number (BQ24650) and identical electrical specifications. The difference is in the reel packaging suffix — RVAT is Tape & Reel, while RVAR is a different reel quantity or orientation. They are functionally interchangeable on the board, but confirm the reel format matches your pick-and-place setup before ordering.
