Dajiqun at the 2025 Shanghai Auto Show, Showcasing Multiple Key "Chip" Trends in Automotive Electronics Upgrades
Dajiqun Electric Multi Field Automotive Application Solution Technology Empowerment, Innovation Leading
1.Multi category products empower 48V architecture upgrade
The 48V system is becoming a consensus in the field of electric vehicles, gradually extending from hybrid models to pure electric platforms, and moving from functional supplementation to system level reconstruction. Its technological breakthroughs and cost optimization will deeply reshape the industry chain ecology. In the 48V architecture system, Ruiyang Semiconductor has mass-produced or sample ready interface products, current detection products, power controllers, intelligent power switch controllers, and other products.
2. Empowering OBC technology to achieve multi in one and high integration
Regarding the current status and trends of OBC technology for electric vehicle on-board chargers, multi in one and high integration are key factors. Ruiyang Semiconductor provides solutions for OBC from power management to communication interconnection through the technology path of full link analog chips. Whether it is the integrated power switch primary feedback isolated power supply TPQ5180Q, the voltage reducing converter TPP36307Q/TPP36609Q supporting a wide input voltage of 3V-36V, or the isolated drive TPM5350Q, the power management and drive chips of Ruiyang Semiconductor have been specially optimized to improve the efficiency and power density of electric vehicles.
3. Escort cockpit intelligent connectivity upgrade
The cockpit remains the key to differentiated competition among new cars, with the in car infotainment system becoming its core selling point. The trend towards multi screen integration, computing power reconstruction, and scene ecology is significant. As a chip intensive system component, achieving efficient power management for information and entertainment systems has become a key layout. Ruiyang Semiconductor provides a wide range of power management products and technical solutions, such as PMIC TPU25401 series, first level Buck TPP36609Q/TPP36307Q, antenna LDO TPL8771Q/TPL8772Q, high side switch TPS42S40Q/TPS42Q20Q, and so on. These automotive grade products are widely used in systems such as in car entertainment, intelligent driving, automotive displays, domain controllers, and battery power supply.
4. Hardcore technology supports innovation in vehicle control
Vehicle body control is becoming a focal area of innovation in new energy vehicles, and technology has undergone structural changes. Ruiyang Semiconductor can provide key support for vehicle body control, from power management to communication interconnection. The control scheme of Ruiyangxin electric vehicle body includes CAN SBC TPT1169Q, LIN SBC TPT1028Q, Tracker LDO TPL8601Q/TPL8602Q/TPL8650Q, Watchdog LDO TPL8536Q/TPL8556Q, eFuse controller TPS60C01Q, ORing controller TPS65R01Q, etc. In some electronic control units in cars, such as wiper control modules, seat heating modules, steering wheel heating modules, etc., LIN communication is usually used, and the TPT1028Q with built-in LIN transceiver and low dropout LDO provides a solution suitable for the internal sub network of the car. High integration effectively reduces board level area, thereby reducing system costs.
