Integrated circuit e.g. scalable high speed current driver, for switching high current, has output terminal connected with electricity generating units, and supply and output terminals that are parallelly switched on substrate

摘要

The circuit (10) has sub-circuits (20-1-20-4, 20-50) arranged next to each other and located on a common substrate. Each sub circuit comprises fast switching electricity generating units (50, 55) for providing a partial stream of high current to be switched. A supply terminal (95) generates a power supply voltage, and an output terminal (90) is connected with the generating units. The supply terminal and the output terminal are parallelly switched on the substrate. Each sub circuit comprises a position input (30) for generating a reference voltage for adjusting the generating units.
