Features and Benefits

Automotive design engineers are challenged with balancing the increasing demands for laptop-class charging inside the vehicle with tight packaging constraints and cost pressures. Delivering higher wattage requires advanced management of heat, wiring complexity and vehicle power budgets.

Molex provides scalable USB-PD architectures with up to 180W total output, intelligent load and thermal management, and vehicle network integration designed for centralized and zonal electrical systems. Molex solutions enable dynamic power sharing and LIN/CAN integration within compact 20.00mm-height modules, enabling sustainable performance for real-world conditions.

Scalable High-Power Architecture

Rising power expectations increase cost and thermal burden. Molex offers flexible 45 to 180W USB-PD platforms with intelligent power sharing and dynamic switching, preserving system efficiency while maintaining the user experience.

Intelligent Thermal and Load Management

High power output in compact spaces requires active control. Molex load-shedding logic, high-efficiency DC-DC design and optimized thermal paths protect the vehicle electrical system while sustaining performance in variable ambient conditions.

Vehicle Architecture Integration

Supporting network-aware modules that optimize electrical system performance, Molex USB solutions support LIN and optional CAN integration, 48V compatibility and centralized power designs for next-generation software-defined vehicles.
