mouser.com/vishay / 3 Look inside any car built in the last decade, and you'll find a dizzying array of electronic systems, each of which requires myriad components designed to deliver accurate and reliable performance in harsh operating conditions. To meet this need, Vishay manufactures a broad range of passive and active discrete components that can withstand the high temperatures and peak transients of automotive systems, from engine control to infotainment and multi-phase converters in advanced driver assistance systems. The company's devices also support the innovative applications in today's hybrid and electric vehicles, including traction inverters, DC/DC converters for 48V power subsystems, battery management with cell balancing, on-board and off-board battery charging, energy recuperation systems, and more. Vishay has established its own Automotive Grade standard for its electronic components destined for this wide range of automotive applications. With the ultimate goal of zero defects, zero incidents, and zero failures, Vishay's Automotive Grade standard incorporates key automotive industry quality initiatives. The process begins with a robust design policy in which new and modified FOREWORD products are developed using design rules, failure modes and effects analysis (FMEA), and lessons learned. Testing to failure confirms that design margins meet the demands of automotive use. Automotive Grade products are qualified to the latest AEC qualification and presented for approval using production part approval process (PPAP). They are produced in facilities certified to IATF16949, and product families are verified to AEC Stress Test Qualification standards every two years. For continuous improvement, error proofing is performed to identify and eliminate potential causes of defects during the entire process. Only components that fulfill all of these stringent requirements earn the Automotive Grade stamp on their datasheets. In the following pages, we explore three automotive categories and how Vishay's Automotive Grade diodes and rectifiers, MOSFETs, optoelectronics, resistors, inductors, and capacitors meet their specific needs. The first category is 48V systems. Here we outline a complete 3kW 48V/12V buck-boost converter design, a 25kW inverter with a 3-phase topology for hybrid motor drives, and an eFuse for safely connecting and disconnecting high current loads to the battery. The second category is electric car battery charging management. In this section, we explore a 22kW onboard charger (OBC) that operates from a 3-phase input voltage; the use of an optocoupler with a phototransistor output to maintain a safe galvanic isolation barrier between high- and low-voltage buses; employing a linear optocoupler as a cost-effective approach to isolating voltages and currents in high-voltage battery packs, and replacing conventional mechanical relays with Vishay's Intelligent Current Sense and Safety Switch (ICSS). The final category is sensors for the dashboard. Here we discuss Vishay's optoelectronic sensor devices that enable Human Machine Interaction. These automated systems monitor user input and lighting conditions so that drivers can keep their eyes safely on the road. We invite you to continue reading about how our solutions are essential to your automotive designs. ▼ MUSTAFA DINC has over 23 years of experience in the automotive industry, currently serving as Vishay Intertechnology's Vice President of Business Development Automotive. He joined the company in 1999 as an automotive field application engineer and went on to become Senior Director of Global Automotive Field Application Engineering and EU FAE Engineering. At Vishay, Mr. Dinc has worked with a wide variety of product lines—from semiconductors to passive components—in most automotive designs for applications, including Powertrains, Chassis, ADAS, EV/HEV, Sensors, and more. He has also been deeply involved in product definitions for 48V mild hybrid vehicles, onboard chargers for electric and plug-in hybrid electric vehicles, and DC/DC converters for hybrid vehicles. He holds a Diplom-Ingenieur (Dipl.-Ing.) in electrical engineering and electronics from RWTH Aachen University in Germany.
