Abstract: A transformer based digital isolator is provided that has improved immunity to common mode interference. The improved immunity is provided by placing the transformer in association with an H-bridge drive circuit, and taking additional effort to tailor the on state resistance of the transistors to control a common mode voltage at the transformer.
