A circuit includes a pair of high side transistors, a pair of low side transistors, a first sense resistor coupled to one of the low side transistors at a first sense node, and a second sense resistor coupled to another of the low side transistors at a second sense node. The first and second sense resistors couple together at a ground node. The circuit includes a first switch network coupled to the first sense resistor, a second switch network coupled to the second sense resistor, a first pair of switches configured to selectively provide a potential of the ground node or a potential of the first sense node as a ground potential to the first switch network, and a second pair of switches configured to selectively provide the potential of the ground node or a potential of the second sense node as a ground potential to the second switch network.
