CS3361G AWLYWW CS3361 Alternator Voltage Regulator FET Driver The CS3361 integral alternator regulator integrated circuit provides the voltage regulation for automotive, 3phase alternators. It drives an external logic level N channel enhancement power FET www.onsemi.com 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. SOIC14 This IC has customized current sense circuitry enabling it to drive D SUFFIX 14 FET transistors. The CS3361 is available in an SOIC14 package.
