L9301 – Control Module Power Switch Load Driver IC for Automotive ECU

The L9301 is a high-side power switch and load driver IC designed for automotive control modules.

It integrates multiple protected output channels for driving resistive, inductive, and capacitive loads.
Typical applications include engine control units, transmission modules, and body control systems.

This chip provides diagnostic feedback for open load, overcurrent, and overtemperature conditions.
It operates over a wide supply voltage range suitable for 12V and 24V vehicle systems.

If your control module requires reliable load driving with self-protection features, the L9301 is a common choice.
It replaces faulty drivers that no longer switch correctly or have lost diagnostic capabilities.

Each unit is carefully removed from functional donor modules and tested for basic output integrity.
Please verify that your original chip marking reads “L9301” before ordering.

This IC is ideal for ECU repair specialists, remanufacturers, and automotive electronics workshops.
Using it can restore full load driving functionality to a control module without replacing the entire unit.
