Abstract
An apparatus and method of determining the junction temperature (Tj) and drain-source current (Ids) of a standard FET within a multi-FET module includes a control IC managing one or more 3 terminal standard FETs within the same package, calculating Tj and Tds for one or more FETs in one or more packages, and protecting each FET against short circuit faults while allowing high current transients, such as inrush currents from a lamp load.
