Abstract
Systems and methods relating to voltage monitoring across isolation barriers are disclosed herein. In one example embodiment, an isolation system includes a low voltage circuit portion including a first control logic portion, and a high voltage circuit portion including a second control logic portion and an analog-to-digital converter portion. The system further includes a first transistor device having a first terminal coupled at least indirectly to a first connection having a first voltage level and a second terminal coupled at least indirectly to a second connection having a second voltage level. The first control logic portion governs provision of an output signal generated based at least indirectly upon the second voltage level. Due to a galvanic barrier, the output signal can be provided for receipt by another device in a manner that avoids exposure of that device to an undesirably high current or power level.
