CS3341/3351/386/387 CS3341/51 CS386/387 Alternator Voltage Regulator Darlington Driver Description 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 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 CS386 and CS387 are available as Flip Chips.
