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:
Hall switch circuitry;
load switch circuitry coupled to the Hall switch circuitry; andan integrated circuit package comprising a current input and a current output, a current flow from the current input to the current output controlled by the load switch circuitry; anda leadframe disposed in the integrated circuit package, wherein the Hall switch circuitry is arranged on a first, to 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 leadrame is configured to attach opposing the first side,wherein the current output is configured to be coupled to an external load to be switched.
