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.
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.
