The BQ24103RHLRG4 is a constant-current, constant-voltage Li-Ion/Li-Pol charger from TI's bqSWITCHER series, rated for a maximum charge current of 2A and a battery pack voltage of 8.4V — that's a 2-cell series stack, fully charged. It integrates over-temperature and over-voltage fault protection, so the external protection circuitry can be leaner than a discrete charger design.
Yes. The battery pack voltage is rated at 8.4V, which is the full-charge voltage for a 2-cell series Li-ion or Li-Pol stack. The charger handles 1 or 2 cells.
The maximum charge current is 2A. The charge current is constant and programmable via an external resistor or the timer feature.
