ON Semiconductor's key automotive solutions and strategies
As one of the world's leading suppliers of the top ten energy-efficient automotive silicon solutions, ON Semiconductor has a strong momentum in automotive electronics, with revenues increasing by nearly 300% compared to a few years ago, especially in the automotive image sensor sector and the AFS market. It has maintained its number one position in the world and will continue to provide a comprehensive product lineup and solutions for the automotive market development trend and continue to promote automotive innovation.
Car electrification
With the increasingly stringent requirements of the government and consumers for fuel efficiency, energy conservation, pollution reduction and environmental protection, various new energy vehicles such as HEV/EV/PHEV have been vigorously developed. ON Semiconductor offers field-stop IGBTs, energy-efficient FETs, power integrated modules, gate drivers, intelligent power modules, application-specific integrated circuits (ASICs), and specialized standard products (ASSP) to support automotive electrification. The development of new energy vehicles first requires the transformation of various energies. In order to continuously improve the efficiency of various energy transformations, ON Semiconductor focuses on strengthening innovation in the following aspects:
1. Develop various energy-efficient power electronic devices, such as high-power IGBTs and power MOSFETs with extremely low on-resistance, to reduce switching losses, thereby improving the efficiency of conversion from electrical energy to mechanical energy. Take the Power Integration Module (PIM) NXH80T120L2Q0PG as an example, using ON Semiconductor's proprietary trench second-generation field stop technology (FSII) and innovative packaging technology to provide over 98% energy efficiency, junction temperature up to 175 °C, reliable Extremely high. The low on-resistance MOSFETs offer a compact, high thermal efficiency package.

2. Develop various DC-DC converters to ensure high conversion efficiency of energy from one voltage level to another, such as from 48 V to 12 V, from 300 V to 48 V, from 12 V to 220 V and so on.
In addition, for the high temperature and harsh conditions under the hood of the car, ON Semiconductor introduced the IPM STK984-17X series of intelligent power modules, integrated intelligent sensorless brushless DC motor (BLDC) controller LV8907, 6 independent MOSFETs, precision shunt Resistors, thermistors, and system peripheral components. The LV8907 does not require any position sensor, preloads the configuration registers, requires no software, and can drive the motor in stand-alone mode. Without the need for an external system controller, the LV8907 also integrates a LIN transceiver to provide an advanced motor drive solution based on LIN. The STK984-17X is used in automotive cooling fans, electric oil pumps, fuel pumps, electric water pumps, etc. It does not require any external microcontrollers. It uses a unique insulated metal substrate technology (IMST) to support the design of no-board, significantly reducing the system. Space, weight and cost provide energy efficiency and reliability, simplify design and speed time to market.
Active safety and autonomous driving
With the continuous improvement of people's awareness of safety, the active safety system has been continuously applied in the car. In particular, ADAS has made great progress with various sensors, showing the development of blowout. For such applications, ON Semiconductor offers image sensors, intelligent passive sensors and other solutions that are fully compliant with the Automotive Safety Integrity Level (ASIL B) ISO26262.
Image sensors for vision applications (such as reversing images and panoramic parking image systems), ADAS applications (such as blind spot detection, lane departure warning, collision avoidance and active cruise control, pedestrian detection, traffic signal recognition) and new fatigue detection, gestures Identification (inside the cabin) and mirror replacement. With more than 10 years of experience in providing CMOS image sensors for the automotive market, ON Semiconductor is the world's No. 1 market supplier of ADAS, providing image sensors with excellent low-light performance, superior image distortion correction, and high dynamic range. (HDR), automotive-grade operating temperature range and high reliability and quality. For example, the company's latest CMOS image sensor AR0136AT, which uses back-illuminated (BSI) sensor technology, provides best-in-class performance, providing four times the low light-to-noise ratio (SNR) and 40% more visible light sensitivity than the current leading AR0132AT. And boosts near-infrared (NIR) performance by more than 60%. The company's new line of image coprocessors, the AP020x, enables the HDR 1080p automotive imaging system to combine a company's high-performance 2 megapixel sensors such as the AR0230AT and 1 megapixel sensors such as the AR0140AT, AR0132AT and AR0136AT to provide a complete and complete reversing image.
