MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA
SYSTEM/APPLICATION INFORMATION
INTRODUCTION
The 33099 is specifically designed for regulation of an
automotive system voltage using diode-rectified alternator
charging systems commonly found in automotive applications.
The 33099 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 owing 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 terminals 7 and 8 being connected to ground.
The 33099 provides a regulated voltage feedback system to
activate the alternator field current in response to system load
current. The output voltage is monitored by an internal voltage
divider scheme and compared to an internal voltage ramp
referenced to a bandgap voltage. The 33099 regulates the
system voltage to 14.8 V for the DW suffix and to 14.6 V for the
CDW suffix 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.
