摘要： A load driver system for integrally controlling the flow of current through a number of inductive loads of an internal combustion engine, particularly the flow of current through a fuel injector solenoid and an engine brake solenoid during the operation of an engine cylinder, is provided. In one embodiment of the load driver system, a single multiplexed high side driver is connected to inputs of both solenoids, and separate low side drivers are connected to outputs of each of the solenoids. In an alternative embodiment, separate high side drivers are connected to inputs of each of the solenoids, and a single multiplexed low side driver is connected to the outputs of the solenoids. In another alternative embodiment, a single multiplexed high side driver is connected to the input of the fuel injector solenoid, the input of the engine brake solenoid is connected to the output of the fuel injector solenoid, and separate low side drivers sharing a common sense resistor are connected to outputs of each of the solenoids.
