Brushed DC Motor Driver

The CS3341/3351 Integral Alternator Regulator ICs provide voltage regulation for automotive three-phase alternators. It drives an external power Darlington transistor used to control the alternator field current. In the event of a charge fault, a lamp output pin is provided that drives an external Darlington transistor capable of turning on a fault indicator light. Conditions of overvoltage or absence of stator signal activate the light output. The CS3341 and CS3351 use SO-14 encapsulation.
