Alternator Voltage

Regulator Darlington Driver

The CS3341/3351/387 integral alternator regulator integrated circuit

provides the voltage regulation for automotive, 3−phase 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 SOIC−14 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.
