How we can help
We have developed a unique expertise on providing over current protection in many applications. We want to make this expertise available to you. We can help with your design in a couple of ways.
First, over the years, we've compiled a list of issues that commonly come up when incorporating over current protection and OCD's into circuit designs. Based on this list, we've developed a couple of application notes addressing these issues. Also, IsoSense recently published a paper presenting a novel approach for over current protection. This paper and the application notes are available here.
A second way we can help is with design assistance, either via E-mail or over the telephone. While we've shared much of our experience in our application notes and paper, we can also provide ideas and solutions to address more obscure issues and problems. We look forward to the opportunity to work with you on your design.
