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 by connecting pins 7 and 8 to ground.
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.
