Technical Support

LiTong provides comprehensive technical documentation for AutoChips products including detailed datasheets with electrical specifications and timing diagrams, application notes covering common automotive design scenarios, reference designs with complete schematics and PCB layouts, and AUTOSAR MCAL drivers for software development. All documentation is available in English and Chinese and can be downloaded from our website or requested directly from our FAE team. We also provide customized application notes for specific customer requirements.

Browse our technical library or contact LiTong FAEs for specific documentation requests.

LiTong offers free samples for qualified automotive design projects. To request samples, contact our sales team with your company information, project details, and required part numbers. Samples typically ship within 2-3 business days for standard products. For automotive qualification requirements, we can provide AEC-Q100 compliance certificates and PPAP documentation. We also provide evaluation kits that include multiple related products for comprehensive system evaluation.

Contact LiTong sales with your automotive project details to request samples for evaluation.

LiTong provides comprehensive design support services including product selection guidance based on automotive application requirements, schematic review and optimization suggestions, PCB layout recommendations for EMC compliance, AUTOSAR software integration support, and functional safety consulting for ASIL applications. Our FAE team has extensive experience with AutoChips products across passenger vehicles, commercial vehicles, and new energy vehicle applications. We also offer on-site support for complex projects and can provide customized training for customer engineering teams.

Engage LiTong FAEs early in your automotive design cycle for optimal product selection and application guidance.

For troubleshooting assistance, first review the datasheet and application notes for common issues and recommended configurations. Check power supply sequencing, decoupling capacitor placement, and signal integrity. Verify AEC-Q100 qualification requirements are met for automotive applications. If issues persist, contact LiTong technical support with detailed information including schematic snippets, scope captures of problematic signals, and description of observed behavior versus expected behavior. Our FAE team can provide remote debugging support or schedule on-site visits for complex automotive issues.

Document your issue thoroughly before contacting support. Include schematics, waveforms, and detailed problem description.

AUTOSAR MCAL (Microcontroller Driver) software is available for AutoChips automotive MCUs. The MCAL drivers provide standardized software interfaces for microcontroller peripherals including GPIO, ADC, PWM, CAN, LIN, and SPI. The drivers are compliant with AUTOSAR 4.x standards and support various compiler toolchains. AutoChips provides MCAL drivers, configuration tools, and integration guides. LiTong can provide MCAL software packages and technical support for AUTOSAR integration.

Contact LiTong to request AUTOSAR MCAL packages and integration support.

Standard lead time for AutoChips products is 6-8 weeks for moderate volumes. LiTong maintains safety stock of popular automotive products for immediate delivery. For large automotive production orders, lead times can be negotiated with factory support. We recommend customers provide rolling forecasts to ensure supply continuity. For urgent automotive production requirements, please contact our sales team to check current inventory status and expedite options. Long-term supply agreements are available for high-volume automotive customers.

Plan procurement with standard 6-8 week lead times. Contact sales for current stock and expedited delivery.

LiTong offers product training and application workshops for customer engineering teams. Training topics include AutoChips product portfolio overview, automotive MCU selection guides, motor control design best practices, functional safety implementation, and AUTOSAR software development. Training can be conducted at customer facilities, LiTong offices, or via web conference. Customized training programs can be developed for specific customer needs including hands-on workshops with evaluation boards.
