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.
