ATIC39-B4 Automotive Computer Board Injector Driver IC – Highly Integrated Fuel Injection Control for Engine Management Systems

ATIC39-B4 is an injector driver integrated circuit specifically designed for automotive engine control units (ECUs).
It features multiple low-side or high-side drive channels to precisely control injector opening and closing timing, adapting to fuel demands under various operating conditions.
Manufactured with advanced BCD technology, the IC supports high operating voltage and high peak current output, while offering fast demagnetization to ensure reliable injector turn-off.
Built-in over-current protection, thermal warning, and short-circuit protection enable stable operation in harsh environments such as high temperature and electromagnetic interference inside the engine compartment.
Its compact package facilitates high-density PCB layout and is compatible with modern automotive electronics manufacturing processes.
The ultra-fast response time allows per-cylinder closed-loop injection regulation with a microcontroller, helping reduce fuel consumption and meet stringent emission standards like Euro 6 and China 6.
Whether for ECU aftermarket repair, board refurbishment, or new powertrain module development, ATIC39-B4 delivers an efficient and reliable injector driving solution.
