Abstract
In some examples, a system comprises a bi-directional gallium nitride (GaN) device including first and second switches and a substrate, the first switch including a first gate and a first source, the second switch including a second gate and a second source, and the substrate shared between the first and second switches. The system include a third switch coupled to the first source and the substrate. The system includes a fourth switch coupled to the second source and the substrate and a comparator having inputs coupled to the first and second sources and outputs coupled to the third and fourth switches.
