CS387H中文资料安森美半导体数据手册PDF规格书

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.
