CS3361YDR14

The CS3361 integral alternator regulator integrated circuit provides the voltage regulation for automotive, 3–phase alternators. It drives an external logic level N channel enhancement power FET 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. A STATOR Power Up feature is incorporated for systems which require power up activation by sensing the crank cycle of the starter at the stator. This eliminates unnecessary current drain when the ignition is turned on, but the car is not running.
The CS3361 is available in an SO–14 package. This IC has customized current sense circuitry enabling it to drive FET transistors.
