30520 Diesel Injector Driver IC for Automotive ECU – Common Rail Fuel Injection Control Module

The 30520 is a dedicated driver IC designed for diesel fuel injection control in automotive engine control units (ECUs).

It provides high-current sinking capability to directly drive solenoid-type injectors in common rail diesel systems.

Operating voltage range supports 12V and 24V vehicle electrical systems, making it suitable for light-duty trucks, heavy-duty trucks, and off-highway diesel engines.

Built-in overcurrent protection and thermal shutdown ensure reliable operation under harsh under-hood conditions.

The logic input interface is compatible with 3.3V and 5V microcontrollers, simplifying integration into existing ECU architectures.

Fast turn-off with active clamping reduces inductive flyback and improves injection timing accuracy.

This chip is widely used for diesel injector control modules, aftermarket ECU repairs, and custom engine management system development.

Each unit is tested for peak current up to 20A and holding current up to 5A, matching typical diesel injector requirements.

Applications: Common rail diesel ECUs, injector drive boards, fuel system service tools, automotive electronics repair.

Features: High-side and low-side configurable, short-circuit protection, diagnostic status output, small surface-mount package.
