MC33099 : Alternator Voltage Regulator with Load Response
Control - GM Type
The MC33099 is specifically designed for regulation of an
automotive system voltage using diode rectified alternator charging
systems commonly found in automotive applications. The MC33099
provides either an analog or digital duty cycle control of an ON/OFF
ratio of an alternator field current at a fixed frequency. This
provides for a Load Response Control (LRC) of the alternator field
current at low engine RPM to eliminate engine speed hunting and
vibration due to abrupt torque loading of the engine when a sudden
electrical load is applied to the system. Four LRC rates are
selectable using a combination of Pins 7 and 8 being connected to
ground.
