The supply for the output stage is fed to pin 6 and the output stage ground is connected to pin 4. The output transistors of the class-B output stage can each deliver 0.75 A maximum. The maximum voltage for pin 5 and 6 is 60 V. The output power transistors are protected such that their operation remains within the SOAR area. This is achieved by the co-operation of the thermal protection circuit, the current-voltage detector, the short-circuit protection and the special measures in the internal circuit layout. Driver and switching circuit Pin 1 is the input for the driver of the output stage. The signal at pin 1 is also applied via external resistors to pin 3 which is the input of a switching circuit. When the flyback starts, this switching circuit rapidly turns off the lower output stage and so limits the turn-off dissipation. It also allows a quick start of the flyback generator. External connection of pin 1 to pin 3 allows for applications in which the pins are driven separately. Flyback generator During scan the capacitor connected between pins 6 and 8 is charged to a level which is dependent on the value of the resistor at pin 8 (see Fig.1). When the flyback starts and the voltage at the output pin (pin 5) exceeds the supply voltage, the flyback generator is activated. The supply voltage is then connected in series, via pin 8, with the voltag
