MOTOROLA ANALOG IC DEVICE DATA
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.
