Product details

What the 16V supply and 2A charge current mean for your BOM

The BQ24103ARHLRG4 is a bqSWITCHER™ series Li-Ion/Polymer charger IC from Texas Instruments, accepting a maximum supply voltage of 16V and delivering a programmable charge current up to 2A. The 16V input ceiling means it can handle a 12V wall adapter or a 5V USB source without an external pre-regulator, but a 24V industrial rail is out of range — plan the upstream supply accordingly. At 2A max charge current, the thermal dissipation in the 20-VFQFN Exposed Pad package needs a solid PCB copper pour under the pad; the datasheet layout note is worth following for full current delivery without thermal foldback.

Frequently asked questions

How can I order the BQ24103ARHLRG4 or check stock?

The BQ24103ARHLRG4 is an Active Texas Instruments part supplied in Tape & Reel. Submit an RFQ with your target quantity; we will confirm lead time and pricing against current distributor and factory availability. No stock count is published here.

What battery chemistry does the BQ24103ARHLRG4 support?

It supports Lithium Ion/Polymer chemistry, with a battery pack voltage of 8.4V — that is a 2-series cell configuration (2S), not a single cell.

Does the BQ24103ARHLRG4 charge a single-cell Li-ion?

No. The battery pack voltage is 8.4V, which corresponds to a 2-series (2S) Li-Ion pack. For a single-cell (4.2V) charger, look at the BQ2407x family or a different bqSWITCHER variant.

What is the difference between BQ24103ARHLRG4 and BQ24103A?

The order code BQ24103ARHLRG4 is the Tape & Reel variant of the base BQ24103A device. The 'R' and 'G4' suffixes indicate reel packaging and a specific lead-free finish (Green). The die and electrical specifications are identical.
