The automobile industry has a history of more than 100 years. The "three modernizations" of automobiles (namely electrification, intelligence, and networking) are driving the entire automobile industry into a new round of revolution. The industry is making rapid progress, and it has also spawned more new Demand, new look.
Automobile electrification has become an unstoppable trend in the automotive industry. The car of the future will not only have driver assistance features, but also highly automated driving functions. Through intelligent technology and Internet of Vehicles technology, cars can realize real-time connection with the outside world, providing drivers with more convenient information services and entertainment experience. At the same time, automotive electronics can also achieve fine control of the cockpit environment, improving the driver's comfort and health. The application prospects of automotive electronics are very broad. We have reason to believe that in the future automotive industry, automotive electronics will play an increasingly important role. Automotive electronics has become a new growth point of the electronics manufacturing industry, providing new development opportunities for manufacturers of special equipment for electronics manufacturing in my country and their upstream industries.
Jinshengyang-Huaqiu Mall Cooperative brand merchant, a domestic power supply solution provider integrating R&D, production, and sales to serve the world, providing one-stop services in the fields of industry, medical care, energy, electricity, rail transit, intelligent transportation, and smart cities It has also delivered product answers in domestic automotive-grade power supply ICs.
SCM1212-Q is pin to pin compatible
As a mature DC-DC power management IC product, SCM1212-Q has taken into account the pin compatibility issue at the beginning of the design, and the pin size is designed to be interoperable with products on the market. It can be switched smoothly without requiring users to significantly change the pcb board. , enjoy a higher cost-effective experience.
SCM1212-Q performance meets mainstream needs
The SCM1212-Q chip has excellent performance, meets the mainstream needs of the industry, and has many key advantages such as high light-load efficiency and soft start. It is also outstanding in the competition with overseas chips. SCM1212-Q has advantages in pin limit withstand voltage, flow capacity ID, frequency, internal resistance RON, etc.
The figure below is a comparison of the detailed parameters of SCM1212-Q with overseas chips and chips from domestic manufacturers. For example, the input voltage of SCM1212-Q is wider than 2.5~6V, and that of overseas chips is 3~5.5V. The VCC/Vin pin of SCM1212-Q has a maximum withstand voltage range of -0.4~9V, while other overseas and domestic manufacturers make -0.3~6V. There is also the ultimate withstand voltage of the D/VD pin, the former meets -0.7~26V, and the latter only achieves ~14V.
SCM1212-Q complies with automotive certification and production control
Jinshengyang's automotive-grade product line is strictly controlled in accordance with the IATF16949 quality management system, and complies with the zero-failure supply chain quality management standard system. Among them, the wafer, assembly, packaging and testing of the SCM1212-Q series meet the third-party AEC-Q100 certification, and the entire process from chip design to packaging and testing is in compliance with the automotive IATF16949 system control.
Not only that, but the reliability of this IC has been verified by the product and the market for many years - the CF0505 series has reached kk-level shipments. The CF0505 series is a mature car-grade power module of Jinshengyang. Jinshengyang has invested its own IC SCM1212-Q in its own products many years ago, making materials independently controllable and providing a strong guarantee for fast delivery.
One-stop "IC+transformer" solution
In addition to single-chip SCM1212-Q and integrated power module CF0505, Jinshengyang can also realize the "IC+transformer" solution to help customers realize one-stop shopping.
Jinshengyang's "IC+transformer" solution includes "chip SCM1212-Q+transformer TTB05xx-1T". Through this combination, it can be used in automotive BMS, PTC heater and other systems to achieve
①3000VAC~5000VAC withstand voltage, the transformer meets the AEC-Q200 standard;
②3.3V/5V input, any voltage output before 5V~20V;
③ Only a simple differential mode inductor is needed to meet the EMI CLASS 3 standard.
More advantages of SCM1212-Q
SCM1212-Q is a push-pull power supply primary-side controller integrated with power MOS tubes. This chip has a wide voltage input range of 2.5~6V, and is compatible with 3.3V and 5V input applications of 3W and below. The limit voltage is 9V, and it will not be damaged under high input voltage impact for 1s. The driving symmetry of the power MOS transistor inside the chip is high, which effectively reduces the bias degree of the push-pull topology.
In addition, it also integrates three key technologies and meets the AEC-Q100 automotive standard to meet the high reliability requirements of customers' products.
Soft start function : avoid damage to the device due to high current impact when starting up, and ensure that it can start with capacitive load in CC load mode;
Output over-current and short-circuit protection : On the one hand, distinguish the judgment and timing of over-current and short-circuit protection to control short-circuit temperature rise, and at the same time ensure the capacitive load when starting up and short-circuit recovery; on the other hand, according to the input voltage and temperature Adjust the protection threshold to avoid affecting the protection function due to changes in input voltage and temperature;
Over-temperature protection : When the temperature exceeds the specified range, the chip will automatically enter the dormant state, and will automatically exit the dormant state when the temperature returns to normal.
summary
Driven by the trend of electrification, intelligence, and networking of automobiles, automotive electronics are becoming more and more important, and the continuous superimposition of downstream demand will accelerate the acceleration of domestic substitution in the automotive electronics supply chain. As a representative of domestic power chips, Jinshengyang has various types of power chips besides the SCM1212-Q mentioned above.
