IC6A930 – Fuel Injector Driver IC for Automotive Engine Injection Systems

IC6A930 is a dedicated fuel injector driver IC designed for modern automotive engine control units (ECUs).

It provides high‑current, high‑voltage switching capability to drive piezoelectric or solenoid fuel injectors with precise timing.

The chip supports peak‑and‑hold current control, which opens the injector quickly with a high peak current and then maintains it with a lower holding current.

This feature reduces injector heating and improves fuel efficiency while ensuring accurate fuel delivery under all engine loads.

IC6A930 integrates overcurrent protection, thermal shutdown, and diagnostic feedback for each injector channel.

It operates from a wide supply voltage of 5.5V to 36V, making it compatible with 12V and 24V vehicle electrical systems.

The device can drive up to four independent injectors in sequential or batch fire modes, supporting common rail and port injection architectures.

With fast response time and low quiescent current, it helps meet stringent emission standards like Euro 6 and EPA regulations.

Each IC is fully tested for short circuit, open load, and ground loss conditions, ensuring robust performance in harsh engine bay environments (‑40°C to +150°C).

IC6A930 communicates via standard SPI or direct PWM inputs, allowing easy integration into aftermarket or OEM ECU designs.
