Current sharing architecture for combination charger
First Claim
1. A method of controlling a charger apparatus that includes a first port and a second port of a different type than the first port, the method comprising:
- receiving a DC power signal generated from an AC input signal provided to the charger apparatus;
determining whether a load current being provided to the second port is above a threshold level;
responsive to determining that the load current being provided to the second port is above the threshold level, (i) causing the first port to advertise a first current at a level that is less than a maximum current level that may be advertised at the first port, and (ii) causing the second port to advertise a second current at a level that is equal to a maximum current level that may be advertised at the second port.

Abstract
A charger apparatus a first port, a second port, a first circuit coupled to the first port, and a second circuit coupled to the second port. The charger also includes a controller, wherein the first circuit and the second circuit each receive a DC power signal generated from an AC input signal, and wherein the controller is structured and configured to determine whether a load current on the second circuit is above a threshold level and responsive to determining that the load current is above the threshold level, (i) cause the first circuit to advertise the first current at a level that is less than a maximum current level that may be advertised at the first port, and (ii) cause the second circuit to advertise the second current at a level that is equal to a maximum current level that may be advertised at the second port.
