Patent attributes
A signal isolator integrated circuit package includes a first circuit having a first input and a first output, a second circuit having a second input and a second output, an isolation barrier layer between the first circuit and the second circuit, wherein the second output of the second circuit is coupled to the first input of the first circuit through the isolation barrier. The signal isolator includes a comparator configured to compare the first input of the first circuit to the second output of the second circuit. The second output can be configured to convey at least three states, including a first state indicative of a logical high of an input signal received at the first input, a second state indicative of a logical low of the input signal, and a third state indicative of a fault condition.
