The CS3341/3351 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 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 SO-14 packages.
