MC33099数据手册恩XP中文资料规格书

描述 Description

Overview 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.
