Abstract: PURPOSE:To decide the hysteresis operating value depending on a current, to reduce the dependancy of a power voltage and to make the output current constant by adopting the specific circuit constitution combined with a constant current source and a current mirror circuit comprising resistors, a diode and two transistors (TR). CONSTITUTION:The circuit has the 1st stable state where a TRQ1 is turned on and Q2, Q3 are turned on and the 2nd stable state where the TRQ1 is turned off and Q2, Q3 are turned off and an output current IOUT to an input voltage VIN shows a hysteresis characteristic. When the Q2 is turned on, the IOUT flows to the Q3, a resistor R1, the Q2 and an R2 and a constant current Ic flows to the resistor R2 via the base of the Q2 and Q3. In this state, when the value of the resistor R1 is decided properly, the IOUT is a constant current. The IOUT is zero when the Q2 is turned off. The threshold value of the input voltage VIN to change the output current IOUT from a high current to a low current or conversely to change from a low current to a high current depends on the constant current Ic and the IOUT.
