Integrated hall-controlled switch devices

摘要

Embodiments relate to Hall-controlled switch devices. In an embodiment, a Hall switch and a load switch are integrated in a single integrated circuit device. Embodiments can provide load switching and optional simultaneous logic signaling, for example to update a microcontroller or electronic control unit (ECU), while reducing space and complexity and thereby cost.

主权项

1. A Hall-controlled device comprising:
an integrated circuit package; Hall switch circuitry disposed in the integrated circuit package; load switch circuitry coupled to the Hall switch circuitry and disposed in the integrated circuit package; and a leadframe disposed in the integrated circuit package, wherein the Hall switch circuitry is arranged on a first, top side of the leadframe configured to face a magnetic field source and the load switch circuitry is arranged on a second, bottom side of the leadframe configured to face a circuit board or other mounting surface to which the leadframe is configured to attach opposing the first side.
