Abstract:
1. A magnetic field sensor-controlled device comprising: magnetic switch circuitry; load switch circuitry coupled to the magnetic switch circuitry; and an 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, wherein the current output is configured to be coupled to an external load to be switched, and the magnetic switch circuitry and the load switch circuitry are disposed in the integrated circuit package, and wherein the magnetic field sensor-controlled device further comprises a leadframe disposed in the package, wherein the magnetic 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 leadframe is configured to attach opposing the first side.
