Abstract
In one example, a circuit includes a pass module, a first sensing module, a second sensing module, a decision module, and a control module. The pass module is configured to modify, based on a control signal, a resistance of a channel that electrically connects an input voltage and a load. The first sensing module is configured to generate a first sensed current. The second sensing module is configured to generate a second sensed current. The decision module is configured to generate a first decision current, generate a second decision current, and generate a composite sensed current based on a summation of the first decision current, the second decision current, the first sensed current, and the second sensed current. The control module is configured to generate the control signal based on the composite sensed current.
