BQ24076RGTR General Description

Furthermore, the BQ24076RGTR's power path management architecture allows the battery to supplement the system's current requirements when the adapter cannot deliver peak currents, thus optimizing power usage. Its three-phase charging process - conditioning, constant current, and constant voltage - is closely monitored to ensure efficient and safe charging without risking overheating
