CS3351 Alternator Voltage Regulator Darlington Driver

The CS3341/3351/386/387 integral alternator regulator integrated circuit provides the voltage regulation for automotive, 3-phase alternators. It drives an external power Darlington for control of the alternator field current. In the event of a charge fault, a lamp output pin is provided to drive an .
