CS3361 Datasheet, PDF (1/8 Pages) Cherry Semiconductor Corporation – Alternator Voltage Regulator FET Driver

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.
