SEMICONDUCTOR TECHNICAL DATA

33099

Adaptive Alternator Voltage

Regulator

The 33099 is designed to regulate the output voltage in diode-rectified

alternator charging systems common 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 accomplished 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 system at low engine RPM. Four LRC rates are

selectable.

ALTERNATOR VOLTAGE

REGULATOR

The 33099 uses a feedback voltage to establish an alternator field current

that is in harmony with system load currents. The output voltage is monitored

by an internal voltage divider scheme and compared to an internal voltage

ramp referenced to a bandgap voltage. This approach provides precision

output voltage control over a wide range of temperature, electrical loads, and

engine RPM.
