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. The CS3361 is available in a 14 lead SO package.
The CS3361 is an integral alternator regulator integrated circuit designed to provide voltage regulation for automotive 3-phase alternators. It drives an external logic level N-channel enhancement power FET to control the alternator field current, ensuring stable charging system performance.
The device includes several protection and monitoring features, such as shorted field protection, temperature compensation, load dump tolerance (80V), and fault indicator lamp output. It activates a warning lamp in the event of no stator signal or overvoltage conditions.
| Supply Voltage Range | 9V to 17V |
