Rev. 2, 06/2001

Advance Information

Alternator Voltage Regulator

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.

The MC33099 provides a regulated voltage feedback system to activate

the alternator field current in response to system load current. The system

voltage is monitored and level shifted using internal resistor voltage dividers,

to compared the level shifted system voltage to an internal voltage ramp

referenced to a bandgap reference voltage. The MC33099 regulates the

system voltage to 14.8 V by generating a Pulse Width Modulation (PWM)

voltage waveform at the gate of an external MOSFET to provide an average

alternator field coil current as a function of the internal voltage comparison.
