48007 – Injector & Fuel Pump Driver IC for Automotive Engine Control Unit (ECU) – Direct Replacement

The 48007 is a dedicated driver integrated circuit designed for both fuel injector and fuel pump actuation in automotive engine control units (ECUs).

This device integrates dual driver channels, enabling simultaneous control of solenoid injectors and a fuel pump relay or direct pump driver. It supports precise current regulation for injector timing and robust switching for fuel pump operation, ensuring optimal fuel delivery and engine performance.

As a common wear-and-tear component on automotive computer boards, the 48007 frequently fails due to thermal cycling, voltage spikes, and continuous high-current switching. Replacing this single IC can restore both injection and fuel pump functions, avoiding the high cost of a complete ECU replacement.

The chip features overtemperature protection, overcurrent shutdown, short-circuit protection, and diagnostic feedback. These built-in safeguards ensure reliable operation under extreme under-hood conditions, with a wide junction temperature range from -40°C to 150°C.

Its standardized pinout allows for straightforward soldering onto original PCB pads, making it a practical choice for professional ECU repair workshops and automotive electronics technicians. The device is compatible with standard 12V automotive electrical systems and supports PWM (pulse-width modulation) for precise injector control.

Whether you are repairing a faulty engine control module, restoring a failed fuel pump driver circuit, or maintaining aftermarket ECUs, the 48007 provides a durable, cost-effective solution for integrated injector and fuel pump drive applications.
