Abstract
A circuit protection device includes a reflowable thermal fuse that shuts off current to a field-effect transistor if the field-effect transistor is overheating. In particular, the reflowable thermal fuse is integrated with the field-effect transistor to provide greater proximity between the field-effect transistor and the reflowable thermal fuse, thus providing efficient and accurate detection of an overtemperature condition in the field-effect transistor.
