Abstract
State-of-the-art electronic circuits heavily utilize the information related to the amount of current being delivered to the load. In safety-critical automotive applications like the airbag squib drivers, it is critical to utilize this information in order to regulate the current that is delivered to the squib. To know about the current that is delivered, a current sensing technique is needed. A sense resistor is typically used to sense the amount of current being delivered to the load, or a senseFET is used in order to sense the amount of current being delivered to the load. In this chapter, the fundamentals of current sensing and how this sensing concept is used to limit the current are being reviewed.
