Abstract: A Hall integrated circuit package includes a Hall integrated circuit and a field line guiding module. The Hall integrated circuit and the field line guiding module are assembled together with a connecting pin of the Hall integrated circuit exposed to outside. Magnetic field causing by carrying current of a cable passing through the field line guiding portion will be detected by the Hall integrated circuit more accurately so that current measurement based on the detection of magnetic field will be more sensitive and precise.

Abstract: A control circuit for Hall-effect switching device is provided. The control circuit can be used in a Hall-effect switching device to control the output of the Hall-effect switching device in response to Hall effect. The control circuit comprises a current source and two pairs of symmetrically arranged bipolar junction transistors (BJT). The particular arrangement of the BJTs allow the Hall-effect sensitivity by the Hall-effect switching device to be enhanced. The Hall-effect sensitivity can be adjusted by varying the current source in the control circuit. Moreover, the control circuit is designed with a double-output feature that allows the Hall-effect switching device to be realizable with a fewer number of transistors, allowing the Hall-effect switching device to operate with a lower working current and a lower starting voltage as compared to the prior art, thus considerably reducing power consumption.
