The MC33092 is specifically designed for voltage regulation and Load  
Response Control (LRC) of diode rectified alternator charging systems, as  
commonly found in automotive applications. The MC33092 provides load  
response control of the alternator output current to eliminate engine speed  
hunting and vibration due to sudden electrical loads which cause abrupt  
torque loading of the engine at low RPM. Two load response rates are  
selectable using Pin 11. The timing of the response rates is dependent on  
the oscillator frequency.

TECHNICAL DATA  
In maintaining system voltage, the MC33092 monitors and compares the  
system battery voltage to an externally programmed set point value and  
pulse width modulates an N–channel MOSFET transistor to control the  
average alternator field current.  
• Forced Load Response Control (LRC) with Heavy Load Transitions  
at Low RPM  
• Capable of Regulating Voltage to ± 0.1 V @ 25°C  
• Operating Frequency Selectable with One External Resistor  
• < 0.1 V Variation over Speed Range of 2000 to 10,000 RPM  
• < 0.4 V Variation over 10% to 95% of Maximum Alternator Output  
• Maintains Regulation with External Loads as Low as 1.0 A  
• Load Dump Protection of Lamp, Field Control Devices, and Loads  
• Duty Cycle Limit Protection
