CS3351 Datasheet Alternator Voltage Regulator Darlington Driver

Manufacturer: onsemi

Overview: CS3341, CS3351, CS387 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.

This datasheet includes multiple variants, all published together in a single manufacturer document.
