Driver stage selection based on noise in galvanic isolation signal transmission

Abstract

According to this disclosure, a first driver circuit may be configured to output a first signal, and a second driver circuit configured to output a second signal, wherein the first signal and the second signal define the differential signal, e.g., for communication over a galvanic isolation barrier. In order to reduce power consumption and also facilitate effective communication in the presence of noise, each driver circuit may include multiple driver stages, and each driver circuit may be capable of using different driver stages at different instances of time, e.g., to change from a low power mode to high power mode, when necessary or desirable. The change from low power mode to high power mode, for example, may be based on detected noise on the communication channels.
