Abstract: An apparatus is disclosed for adaptive switch driving. In an example aspect, the apparatus includes a switching circuit configured to selectively be in a first state that provides an input voltage as an output voltage, be in a second state that provides a ground voltage as the output voltage, or be in a third state that causes the output voltage to change from the input voltage to the ground voltage according to a slew rate. The third state enables the switching circuit to transition from the first state to the second state. The switching circuit is also configured to adjust the slew rate of the output voltage for the third state responsive to at least one of the following: a change in a magnitude of a direct-current supply voltage or a change in a magnitude of an input current.

Abstract: A dual port charging architecture is generally disclosed. For example, the dual charging architecture may include a first board portion having a first battery port configured to be coupled to a first set of battery terminals of a battery, a second board portion having a second battery port configured to be coupled to a second set of battery terminals of the battery, a connection portion electrically coupled between the first board portion and the second board portion, a first power path coupling a power input port of the second board portion to the first battery port via the connection portion, and a second power path coupling the power input port to the second battery port.
