The BQ24070RHLTG4 is a highly integrated Li-ion Linear Charger and System Power-path Management Device targeted at space-limited portable applications. The BQ2407X device offers DC supply (AC adapter) power-path management with autonomous power-source selection, power FETs and current sensors, high-accuracy current and voltage regulation, charge status and charge termination, in a single monolithic device. The BQ2407X device powers the system while independently charging the battery. This feature reduces the charge and discharge cycles on the battery, allows for proper charge termination and allows the system to run with an absent or defective battery pack. This feature also allows for the system to instantaneously turn on from an external power source in the case of a deeply discharged battery pack. The IC design is focused on supplying continuous power to the system when available from the AC adapter or battery sources.
