Allegro has developed a range of high-current automotive-grade current sensors in packages only 1.5mm thick. The Hall sensors are differential to reject common-mode fields – from nearby current-carrying conductors, for example. The devices consist of a precision low-offset linear Hall circuit with a copper conduction path located near the die (see photo). Applied current generates …
