Abstract
One or more embodiments are directed to a battery charger that can support multiple battery applications with a single USB type-C port. The architecture can be easily extended to support more applications such as those including two or more USB Type-C ports by adding additional voltage regulators. Additionally, the architecture can easily be extended to support additional batteries by adding corresponding battery chargers. Some embodiments enable supplying two or more system voltages and charging two or more batteries simultaneously using a single adapter and/or port. Other embodiments enable supplying voltage to On the Go devices from two or more batteries simultaneously.
