40049 Fuel Pump / Injector / Ignition Driver Module Chip

This chip integrates three major functions into a single module: fuel pump relay drive, injector solenoid drive, and ignition coil power drive, specifically designed for multi-channel load control in engine control units (ECU).
Three independent low-side power switches are built in, each featuring overcurrent protection and inductive load clamping circuitry to safely drive fuel pumps, injectors, and ignition coils.
Each drive channel supports up to 5A continuous current and 8A peak current, meeting typical actuator requirements in 12V automotive systems.
An integrated fault diagnostic interface provides open-circuit, short-circuit, or overtemperature status feedback to the microcontroller, simplifying system-level diagnostic design.
Operating voltage range from 6V to 28V with load-dump protection, satisfying automotive-grade power supply requirements.
Housed in a compact multi-pin power package, it saves valuable ECU board space while maintaining good thermal performance.
This module directly replaces or is compatible with many original integrated driver solutions, ideal for engine management system repair, powertrain replacement, and the tuning aftermarket.
Every chip is fully functionally and ESD tested before shipment to ensure long-term reliability under harsh operating conditions.
