Abstract
A driver circuit is configured control one or more bypass transistors. The driver circuit includes a primary supply input connection configured to supply the driver circuit with power from a set of battery cells. The set of battery cells is configured to supply power to a load via a power delivery circuit. The driver circuit also includes one or more secondary supply input connections. The driver circuit is configured to receive information indicating whether an error condition is present in the power delivery circuit and control, based on the error condition being present in the power delivery circuit, the one or more bypass transistors to define a bypass current path. The driver circuit is also configured to receive, via a secondary supply input connection of the one or more secondary supply input connections, power from the bypass current path.
