Overview
Order this document by MC33092A/D Alternator Voltage Regulator The MC33092A is specifically designed for voltage regulation and Load Response Control (LRC) of diode rectified alternator charging systems, as commonly found in automotive applications.
The MC33092A 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.
In maintaining system voltage, the MC33092A 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.
