  • Current detector circuit
    Patent number: 5635823
    Abstract: In a current detector circuit wherein the sense current flowing through a sense transistor for sensing part of the main current flowing through a main element transistor is flowed through the detection resistor to cause the bipolar or MOS control transistor to detect the voltage drop across the detection resistor, a compensation diode connected to the base or gate of the control transistor and the emitter of the sense transistor and a forward bias generation resistor element for generating a forward bias applied to the diode for a time interval during which the main current flows are arranged.
