The CS3341/3351/387 integral alternator regulator integrated circuit provides the voltage regulation for automotive, 3phase 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 external darlington transistor capable of switching on a fault indicator lamp. An overvoltage or no STATOR signal condition activates the lamp output. The CS3341 and CS3351 are available in SO14 packages. The CS387 is available as a Flip Chip. For FET driver applications use the CS3361. Use of the or CS387 with external FETs may result in oscillations.
