BA12003BF SIP14 Automotive ECU Boards 7-Channel Darlington Driver Chip

BA12003BF SIP14 7-channel independent Darlington transistor driver chip used as a low-side switch for automotive Body Control Modules (BCM). Drives vehicle lights, door lock solenoids, wiper motors, instrument cluster LEDs, and fuel injection auxiliary coils. Suppresses reverse high-voltage surges from inductive loads and enables centralized multi-channel load driving, simplifying peripheral circuit board components.
