Filed: 1992-08-31
Abstract: PURPOSE:To allow a current detector which uses a magnetic sensing element in the detection of magnetic flux generated by passing of current in a ferromagnetic core to be usable for both AC and DC and detect the presence of current according to a threshold. CONSTITUTION:The output of a magnetic sensing element 1 which uses a control current source 18 as power supply is input to a differential amplifier 6, amplified at an amplification factor based on the values of resistances 2, 5, smoothed by a smoother comprising a resistor 7 and a capacitor 8, and input to a comparator 13. The output is compared with a reference level based on the values of resistances 9, 10, and the comparison result is output to the outside. The resistance 14 is for providing hysteresis width to the comparator 13. A transistor 17 is used as external output means to provide an open collector output, which is pulled up to VCC by a resistance 35. An internal circuit is thus to comprise a single power source and the amplifier 6 amplifies the micro output voltage of the magnetic sensing element through half-wave rectification.
