Integrated circuit for starter controller has end stage component with switchable current source(s) that holds port pin(s) at high state during at least one operating phase of microprocessor

摘要

The integrated circuit has a resettable microprocessor (2) with at least one port pin (15) coupled to an end stage component (50) with at least one semiconducting component (53) controlling an output line (58). The end stage component has at least one switchable current source (51,52) that holds the at least one port pin at a high state during at least one operating phase of the microprocessor.
