Abstract
Systems and methods for digital isolation in circuits are provided. On power-up in an isolation application, there may be multiple power supplies. For example, one for an input side and one for an output side, both in relation to an isolation barrier. Upon power up, the input and output may not be at the same state. The bias of the output may be the opposite of what is on the input. An isolator solution is provided which integrates the digital isolation into the analog solution. A DC signal corresponds to the static state of the data at start-up and an AC signal is generated when switching begins. In one example, the output level corresponds to the input level when the steady state information is encoded and sent across as an AC signal.
