Automated RDSon characterization for power MOSFETS

This paper presents an automated RDSon characterization test for Power MOSFETS. Considerations for both hardware and software development, and integration have been performed. Raw data can be captured in a single pulse setup by logging the data in a customized spreadsheet. This allows for observing the instantaneous and over time behavior of the device resistance. A qualification of the test was done with packaged devices. It was found that the solution presented here is robust, simple, yet performable with low-cost with of-the-shelf test equipment.
