Under the global trend of intelligence, the rapid development of industrial manufacturing and electric vehicles will enter the field of intelligence. Based on this background, ON Semiconductor has also vigorously researched on intelligent power and intelligent sensing technology, and has launched intelligent power and intelligent sensing solutions suitable for industrial and automotive environments.

In the industrial field, ON Semiconductor mainly focuses on new energy, charging stations and machine vision. The industrial application related to electric vehicles is the charging station, which has PFC, or other AC-DC, DC-DC related chips and solutions. In terms of intelligent perception, ON Semiconductor, as a leader in emerging technologies, has image sensors, special chips for ultrasonic sensors, and new products in lidar. In terms of automotive intelligent power supply, ON Semiconductor has silicon carbide (SIC) and IGBT power module products for electric/hybrid (EV/HEV), as well as power management for automotive CPU, LED lighting and body electronics.

A third party predicts that more than half of the 100 cars sold by 2028 will be electric vehicles, including plug-in, pure electric, etc. It can be seen that the proportion of electric vehicles is increasing year by year, and the demand for IGBT, silicon carbide SiC, automotive-grade IC and MCU has increased significantly. In order to enhance the supply capacity of silicon carbide, ON Semiconductor has completed the acquisition of GTAT, a silicon carbide ingot company. GTAT has strong crystal growth technology and will supply silicon carbide ingots to ON Semiconductor from March 2020.

Modular IGBT/SiC+ direct cooling platform cooling

Silicon carbide technology, whether it is silicon carbide MOSFET or diode, has developed to the second generation, and the second generation has reduced power loss compared to the previous generation. ON Semiconductor has pure SiC products, as well as some hybrid IGBT and SiC modules that are mainly used in industry. These modules are easy to install and have industry standard packages and pins.

On the main drive module of the car, whether it is IGBT or silicon carbide, ON Semiconductor has a gel module with direct cooling, and ON Semiconductor has also introduced a more cost-effective indirect cooling plastic package. In the double-sided cooling module, the IGBT is a smart chip. It mainly has two built-in sensors, one is a temperature sensor. Compared with many NTCs on the market to detect temperature, ON Semiconductor can achieve more accurate temperature detection. Similarly, the current detection is built into the IGBT, and the overall response time is faster, which can better protect the system.

Image Sensor + Lidar

ON Semiconductor‘s products in intelligent perception, the first thing to mention is the image sensor. Through the acquisition of different companies, ON Semiconductor has more than 2,300 patents. In terms of microlenses and CFA, ON Semiconductor has built its own factories, and will gradually replace it with its own chips in the future.

Regarding car image sensing, you will find that there are more and more applications of cameras in the car, whether it is placed in the front end, or for scene perception, or for surround view, etc., as well as some combined applications, such as with DVR or AR , or AD camera + surround view in blind spot. In addition to more and more cameras, the pixels will be higher and higher, from the previous 1 million, 2 million pixels to 8 million pixels.

LiDAR (LiDAR) is also an area of ​​intelligent perception, and more and more LiDAR will be loaded into autonomous or ADAS vehicles in the future. At present, most of the lidars are suitable for the components of avalanche photodiodes (APDs), and the silicon photomultipliers (SIPMs) provided by ON Semiconductor have better effects. Compared with APD, SIPM has better consistency. A single shot can detect a range of 150 m, and with multiple shots, it can reach a range of 300 m. The SIPM product launched by ON Semiconductor can detect the range beyond the 900nm lens, and the cost performance of SIPM is the highest in the industry.

ON Semiconductor builds a better future with intelligent technology

On the industrial side, ON Semiconductor focuses on intelligent power technology to achieve the highest energy efficiency solar inverters, industrial power supplies and energy storage systems, bringing sustainable development to industrial applications. In terms of intelligent perception, ON Semiconductor actively promotes Industry 4.0 to make factories, buildings and homes more intelligent. At present, in the automotive field, ON Semiconductor uses silicon carbide to bring lighter and longer-lasting high-performance products to electric vehicles. In terms of automotive intelligent perception technology, ON Semiconductor uses advanced imaging technology and lidar perception technology to improve the safety of automobiles. Sex and travel experience.
