Abstract: A system may include a first controller and a second controller communicatively coupled to the first controller via a bidirectional communication channel and configured to drive a load in accordance with a target current signal, sample a load voltage of the load at a sample rate substantially slower than a time duration of electrical transients of the load, calculate a resistance of the load based on a current signal and the load voltage and communicate information indicative of the resistance to the first controller at a time interval substantially slower than the time duration of electrical transients of the load, detect when one or more accuracy-reducing events associated with the system occur, wherein an accuracy-reducing event is one which negatively affects accuracy of calculation of the resistance, and modify the information provided to the first controller when one or more accuracy-reducing events occur.

Abstract: A system may include a first power domain defined by a first supply rail and a first ground rail, a second power domain defined by a second supply rail and a second ground rail, and a configurable switch coupled between the first ground rail and the second ground rail such that when the configurable switch is enabled, the first ground rail and the second ground rail are electrically shorted to one another and when the configurable switch is disabled, the first ground rail and the second ground rail are electrically isolated from one another.
