It integrates over-temperature and over-voltage fault protection, so the external protection circuitry can be leaner than a discrete charger design.","metaTitle":"BQ24103RHLRG4 Li-Ion Battery Charger IC, 2A, 8.4V","metaDescription":"Texas Instruments BQ24103RHLRG4 Li-Ion/Li-Pol charger IC, 2A max charge current, 8.4V pack voltage, -40°C to 85°C, 20-VFQFN.
