33099 Datasheet | Freescale Semiconductor

.. Freescale Semiconductor Technical Data Document Number: MC33099 Rev. 6.0, 1/2007 Adaptive Alternator Voltage Regulator The 33099 is designed to regulate the output voltage in dioderectified alternator charging systems mon to automotive applications. The 33099 provides either an analog or digital fixed frequency duty cycle (ON/OFF ratio) control of an alternator’s field current. Load Response Control (LRC) of the alternator field current is acplished by selecting the duty cycle for prevailing engine conditions to eliminate engine speed hunting and vibrations caused by abrupt torque loading of the engine owing to sudden electrical loads being applied to the...
