CS3361
Alternator Voltage
Regulator FET Driver
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.
This IC has customized current sense circuitry enabling it to drive FET
transistors.
The CS3361 is available in an SOIC−14 package.
