ATIC94D1 – High-Current 4-Channel Low-Side Injector and Solenoid Driver IC for Automotive Engine ECU

ATIC94D1 – Quad Low-Side Injector Driver IC

This automotive-grade driver IC is specifically engineered for direct control of fuel injectors, solenoid valves, and other inductive loads in engine control units (ECUs). Widely used in vehicle-specific ECUs, including applications for Mercedes-Benz M272 and BMW N52 engine management systems.

Key Features:

    Four independent low-side output channels for injector and solenoid control

    High peak current capability per channel to drive both high-impedance and low-impedance injectors

    Integrated over-temperature protection with automatic shutdown

    Over-current and short-circuit protection to safeguard the ECU

    Wide operating temperature range: -40°C to +125°C for harsh automotive environments

    Logic-level compatible inputs for direct microcontroller interface

    Robust QFP package for reliable PCB mounting and heat dissipation

Benefits for Your ECU Design:

    Enables precise fuel injection timing under extreme engine conditions

    Reduces external component count with embedded protection circuits

    Supports 12V automotive electrical systems with high robustness

    Fast switching response for optimal injector performance

Applications:

    Gasoline and diesel engine ECUs (including Mercedes M272, BMW N52)

    Direct injection fuel system drivers

    Transmission solenoid control

    Exhaust aftertreatment actuators

    General automotive inductive load switching

This driver simplifies engine management PCB design while ensuring compliance with automotive EMC and thermal requirements for reliable long-term operation.
