Parallel charging architecture
Abstract:
Methods, devices, apparatuses, and systems may provide integrated combined current sensing for parallel charging architecture. In one embodiment a charger includes a first charging device that includes a switching circuit having a switching output configured to be coupled to a first terminal of an inductive element. The first charging device further includes a charging terminal configured to couple a second terminal of the inductive element to a battery terminal to provide a first power source to charge a battery coupled to the battery terminal. The first charging device further includes a charge current sense element coupled between the charging terminal and the second terminal of the inductive element. The charge current sense element is configured to sense a charge current at the charging terminal. The circuit further includes a second charging device that includes a second power source coupled to the second terminal such that the charge current comprises current from the first charging device and the second charging device.
