Abstract
Circuits, devices and systems that include a low voltage test for common mode transient immunity (CMTI). The CMTI test of this disclosure may be used in a variety of applications, such as a data transmission circuit configured to communicate across galvanic isolation. A differential circuit may include two signal paths. For robust common mode transient rejection, the first signal path should be the same as the second signal path. Differences in the resistance, inductance, and capacitance between the two signal paths may result in common mode noise being measured as a differential signal at the output terminals. Devices according to the techniques of this disclosure are configured to enter a test mode to conduct a low voltage test that outputs a measurement of CMTI at any phase of production or field use.
