48128 - Power & Communication IC for Diesel Engine Control Unit (ECU), Automotive Grade

The 48128 is a dedicated power management and communication interface IC for diesel engine control units.

It integrates voltage regulation, CAN/LIN transceiver functions, and diagnostic logic in one package.

This chip ensures stable power delivery to the microcontroller and peripheral sensors in diesel ECUs.

It supports real-time data exchange between the engine control unit and vehicle network systems.

Designed for 12V and 24V diesel electrical architectures, including light-duty and heavy-duty trucks.

Operating temperature range from -40°C to +125°C, suitable for under-hood and engine-bay conditions.

Low quiescent current minimizes battery drain during engine-off periods, critical for commercial fleets.

Built-in overvoltage, undervoltage, and reverse polarity protection for robust automotive use.

The IC provides wake-up capability via CAN/LIN bus, enabling low-power sleep modes.

Fault detection features include short-circuit, thermal shutdown, and open-drain diagnostics.

It reduces external component count, simplifying PCB layout for aftermarket or OEM diesel ECU modules.

Commonly used in diesel engine management systems, fuel injection controllers, and aftertreatment control units.

AEC-Q100 qualified, ensuring long-term reliability in vibration and temperature cycling environments.

Direct replacement for damaged or degraded power and communication ICs in diesel computer boards.

Packaged in a compact, lead-free SSOP for automated SMT assembly.
