Abstract

In some examples, a device includes a control circuit configured to deliver driving signals to a switch. The device also includes a testing circuit configured to cause the control circuit to toggle the switch at a first instance and determine a parameter magnitude at the switch at a second instance after toggling the switch at the first instance by at least determining a voltage magnitude at the switch at the second instance. The testing circuit is also configured to cause the control circuit to toggle the switch after the second instance and determine a parameter magnitude at the switch at a third instance after toggling the switch after the second instance. The testing circuit is further configured to generate an output based on the determined parameter magnitudes at the switch at the second and third instances.
