Automotive electronics can be categorized into several different types such as chassis electronics, engine electronics, driver assistance, transmission electronics, entertainment systems, passenger comfort, and active safety. For any electric system which may include DC/AC, AC/DC, DC/DC the electronic power mechanism such as gate drivers, controllers, converters, and others are desirable. In general, depending on the power supply or vehicle manufacturing requirements the analog, as well as digital controllers, can be selected the parameters such as reliability, cost, flexibility, and integration are taken into consideration.     

Role of Transistors in Automotive Industry

Applications of transistors in automotive electronics as well as electrical systems may include automotive power generation, voltage systems, SMPS (Switched Mode Power Supply), traction inverter, electric drivers, DC to AC converter DC to DC converter, high-temperature requirement, power electronic component, power train system, and many others. In addition to this, several applications based on the power electronics across the automotive power creation system offer several automotive alternatives along with improved competence as well as elevated power, and temperature enduring capacity. It also may include high-power density along with detailed research on the applications of switched-mode power electronics. Armature and field specifications of this alternator are improved by the huge acceptance of power electronics. Such alternators are used across automobile industries to transfer power to the electrical system and batteries.  

SMPS (Switched Mode Power Supply)

The switched-mode power supply is depended on the power electronics devices like semiconductor devices which operate with on state which has 0 voltages as well as off-state which has 0 current. However, to switch such power semiconductor components on and off the (PWM) pulse width modulation technique is utilized. Less immense and small-sized power electronics-based power converters are used for high-frequency switching as such switches is able to operate with the high switching capabilities. In addition to this, limitations could be conquered with the help of a massive gap between semiconductors such as silicon carbide along with a high-operating temperature which enables inserting the circuit with the high-temperature place. However, it has higher thermal conductivity as compared to silicon that will reduce the need for huge copper blocks as well as water jackets. Additionally, silicon carbide has a relatively higher breakdown of electrical energy. Also, it is capable of switching at higher frequency along with low power loss.

Advanced automotive transistors technologies which may include in-car infotainment, all-electric cars, and autonomous driving are some of the major trends across the autonomous industry. In addition to this, automotive vehicles are majorly converting with the “ultimate electronic devices”. However, automotive transistors are predicted to remain a significant growth rate in the coming years. The automotive industry is growing with several innovative features as well as challenges such as autonomous driving, secure & high-speed communication and infotainment, and all-electric cars with high power. However, since the last few years, advancements in electric vehicle sensor have led to highly innovative autonomous driving technologies which allow higher visibility as well as high-level awareness. Hence, the special advanced features of the vehicle may comprise park assistance, adaptive cruise control, pedestrian detection, lane-keep assistance, as well as traffic-sign recognition.

Furthermore, in modern and newest automotive transistors systems as well as subsystems, transistors can come up with an individual component. On the other hand, multiple transistors are generated on a single semiconductor chip. Thus, the combined circuits are called integrated circuits and they are packaged with a high number of leads configured like they are connected through soldered connections with the help of printed circuit board. In addition to this, a printed circuit can be made of a thin insulating board in which conductors are produced which offers the interconnection among the number of integrated circuits to generate an electronic system or subsystem.

According to the latest research, the automotive transistor market may contain the number of administrative policies across the globe to eliminate carbon emissions which have offered higher adoption of ICT-enabled services across the automotive industry. In addition to this, as per the analysis, the global share for analog ICs as well as power transistors for energy management dominated for more than USD209 each vehicle in the year 2017. Moreover, the automotive industry is estimated to account for a substantial growth rate of the global demand for power transmission into the coming years. This industry has become one of the highest applications for power transistors. In addition, growing demand for power transistors and analog ICs is extending as xEV batteries with growing capacity as well as delivering electricity with high voltages. Semiconductor components for PM (power management) may comprise application-based MOSFETs, ICs, MCUs, and driver ICs for the (BMS) Battery Management System. In recent years, the major service providers of such components are worldwide analyzed automotive transistors companies such as Renesas, Texas Instruments, STMicroelectronics, and Infineon. However, as xEV batteries increasing with higher capacity as well as it delivers electricity along with high voltages. In addition to this, the increasing demand for power transistors and analog ICs for circuit protection or conversion is anticipated to increase into the coming future.

According to geographical expansion, the China region accounts for more than 20% of the newest and innovative vehicle sales across the globe. In addition to this, the Chinese government highly supports the advancements of the regional xEV industry across the region. Furthermore, the region has also accounted for the huge significance of the domestic research of GaN as well as Sic automotive devices for the power semiconductors.
