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. ## Sourcing the BQ24103ARHLRG4 — RFQ-based availability The BQ24103ARHLRG4 is supplied in Tape & Reel (TR) for automated assembly. Submit an RFQ for the BQ24103ARHLRG4 to receive a firm lead-time and price commitment tailored to your order volume.","metaTitle":"BQ24103ARHLRG4 Texas Instruments Li-Ion Charger IC – Active","metaDescription":"Texas Instruments BQ24103ARHLRG4 bqSWITCHER™ Li-Ion/Polymer charger IC.
