0D273 Automotive ECU Communication & Injector Drive Chip

0D273 is a dedicated driver IC for automotive engine control units.
It integrates onboard communication protocols with precision injector control.

Key technical features:

    Direct drive capability for up to 4 high-impedance fuel injectors.

    Built-in CAN/LIN transceiver for real-time ECU data exchange.

    Over-current and thermal shutdown protection for harsh automotive environments.

    Operating voltage range: 6V – 36V, compatible with 12V/24V vehicle systems.

    Low ON-resistance (typical < 0.2Ω) minimizes power loss and heat.

Typical applications:

    Aftermarket engine management systems.

    Gasoline and diesel direct injection control modules.

    Universal automotive computer board repairs and upgrades.

Why choose 0D273 for your project?
This chip eliminates the need for separate communication bridges and injector drivers, saving PCB space and BOM cost. It is tested for -40°C to +125°C operation, ensuring reliability under hood. Direct pin-to-pin compatibility with many standard ECU footprints allows easy retrofitting. Whether you are building a custom tune module or repairing an OEM computer board, 0D273 delivers stable timing and high-current drive for precise fuel metering.

Packaging: RoHS-compliant, available in reel or tube.
