摘要: A method and apparatus for sequencing the operation of electronic circuits based upon level voltage provided by an external power supply. One or more supply sequencer may be interposed between one circuits. The comprise a transistor having its high current node coupled to supply, controlling means such as diode resistor, wherein resistor is in turn ground potential. has controlled through input circuit condition received thereby. second set sequenced transitioning potential supplied from operating Multiple versions sequencers used enable sequential entire system during transitions.
