TLE6220GP – Injector Driver IC for Automotive Engine Control Unit (ECU) – Quad Low-Side Driver – Direct Replacement

The TLE6220GP is a monolithic quad low-side driver IC specifically developed for fuel injector control in automotive engine control units (ECUs).

This device integrates four independent low-side driver channels, making it ideal for driving multiple solenoid injectors in gasoline and light-duty diesel engine management systems. Each channel provides precise current regulation and fast demagnetization for accurate fuel metering.

As a common wear-and-tear component on automotive computer boards, the TLE6220GP frequently fails due to continuous thermal cycling, voltage transients, and high-frequency operation. Replacing this single IC can fully restore ECU functionality, avoiding the high cost of complete board replacement.

The chip includes built-in overtemperature protection, overcurrent shutdown, and short-circuit protection for each channel. Diagnostic feedback allows the main microcontroller to monitor channel status. These features ensure reliable performance under extreme under-hood conditions, with an operating junction temperature range from -40°C to 150°C.

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

Whether you are repairing a failed engine control module or maintaining aftermarket ECU upgrades, the TLE6220GP provides a durable, cost-effective solution for multi-channel injector drive applications.
