MONOCHIP CAR ALTERNATOR REGULATOR
Description
Alternator regulator 14IVR-XX, made under the integrated technology is essentially
a monochip voltage regulator for the car alternators with the rectifier nodes on the Zener
diodes. The single chip combines the control functions and the powerful output cascade
with IField=5 A to control the generator excitation circuit. The alternator regulator 14 IVR-XX
does not require application of other external components, which considerably reduces the
system cost as a whole and enhances its reliability.

Interval of the voltages, within which range the microcircuit ensures the voltage
regulation of the car-borne mains, is the regulation range.
When reducing the regulated voltage to the bottom margin of the regulation range
the generation rupture occurs, i. e. the pulses disappear. At the microcircuit output the low
level status is set appropriately (the direct current is applied to the excitation coil of the
alternator).
When increasing the regulated voltage to the regulation range upper margin, the
generation stabilization occurs, i. e. the pulses appear with porosity of Q ≈ 21. The further
increase of the regulated voltage within the rated norm limits on the regulated voltage (at
the temperature of T=(25 ± 3)оС UСС ≈ 18V) does not result in alteration of the output
voltage pulses porosity.
In the middle of the regulation range porosity of the output pulses Q=2±0.1, which is
taken for the regulator adjustment voltage UREG.
The tune-up characteristic of the voltage regulator has a non-linear dependence on
the regulation voltage, which makes it possible to enhance the efficiency of the alternator
current output during the voltage reduction.
