Alternator Voltage
Regulator Darlington Driver
The CS3341/3351/387 integral alternator regulator integrated circuit
provides the voltage regulation for automotive, 3phase alternators.
It drives an external power Darlington 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.
The CS3341 and CS3351 are available in SOIC14 packages. The
CS387 is available as a Flip Chip.
For FET driver applications use the CS3361. Use of the CS3341,
CS3351 or CS387 with external FETs may result in oscillations.

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.
