ABSTRACT:
An integrated anode power stage using one or more Darlington transistors combinations is constituted for currents exceeding 5 amperes and voltages exceeding 200 volts. On a common semiconductor substrate there are provided, in addition to the Darlington circuit or circuits a large number of peripheral components, both active and passive, such as are required for protection, regulation and turning on or off of the final stage for operating an ignition coil in a motor vehicle. By providing these components in basins of the same conductivity type as the base of the power transistor a unit is provided that is economical to make as well as compact and reliable.
