Darlington Lamp Driver
Features
Description
This integrated circuit is a flip
chip lamp driver for use in an
automotive alternator system.
The circuit drives an indicator
lamp located on the dash-
board. Reverse battery protection is provided with internal
diode, D1, and external resistors on B, C1 and C2.
