8 / 20 page 33099 MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA 8 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.
