MC33099 Datasheet | Motorola Semiconductor

Freescale Semiconductor, Inc. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC33099 Rev 4.0, 07/2004 33099 Adaptive Alternator Voltage Regulator The 33099 is designed to regulate the output voltage in diode-rectified 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...
