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.

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.
