Abstract
In described examples, a first and second driver each include a first-rail output transistor including a first terminal coupled to a first power rail and a second-rail output transistor including a first terminal coupled to a second power rail. The first-rail output transistor of each of the first and second drivers includes a second terminal coupled to a second terminal of the second-rail output transistor of an output node of each respective first and second driver. A resistive load includes a first terminal coupled to the first-driver output node and includes a second terminal coupled to the second-driver output node. A sampling circuit generates an indication of an impedance of at least one of the output transistors of the first and second drivers.
