The output voltage of the circuit 4 is set lower than the reference voltage in a steady working mode. The voltage of a load 2 is set at 0 right after the application of a power supply, and a transistor TRQ3 is turned off. After the application of the power supply, the output of the circuit 4 supplies a base current to a TRQ2 via the diode D2 to control the impedance between the collector and the emitter of a series control TRQ1. Therefore both TRQ2 and Q3 work together to produce a constant voltage function. In such a way, the assured starting is made possible under various load conditions.

IPC: H02H3/093
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a controller output circuit which can easily detect an overcurrent with no wrong detection. SOLUTION: The potential equivalent to the drain-source on-voltage VDS( ON) of the FET 161 and 162 is applied to a capacitor 129 through resistors 121 and 122. When the charging voltage of the capacitor 129 exceeds the Zener voltage VZ of a Zener diode 130, the diode 130 conducts and a short circuit current is detected. A capacitor 134 is charged through a resistor 133 when the charging voltage of the capacitor 129 exceeds the reference voltage V1 of a 1st comparator 131. Then an overload current is detected when the charging voltage of the capacitor 134 exceeds the reference voltage V2 of a 2nd comparator 135. If an allowable serge current flows, the charging voltage of the capacitor 134 is kept at a level lower than the voltage V2 of the comparator 135. So that the comparator 135 never outputs an output signal.
