Guide Overview 

Gone are the days when cars could rely solely on 12V electric systems. Today’s vehicles have lots of power-hungry features, such as electrical power steering, pumps, HVAC compressors, and battery packs. To keep pace, the automotive world is migrating to 48V electrical systems. Such systems boost available power to support new power demands. 48V systems allow for thinner wires and smaller connectors which translate into weight, space, and cost savings.

This comprehensive solution guide covers all the aspects of 48V “powernet” designs for automotive systems. From the simplest electronic controller inside traditional cars to the silent hum of electric vehicles, MOSFETs play a crucial role under the hood of any car. Small yet powerful silicon MOSFET discretes can control electric motors, ensure battery charging, distribute power and ensure system safety. You’ll learn about the leading MOSFET and gate driver technology choices, as well as how 48V technologies enable steer-by-wire, advanced driver-assistance systems (ADAS), zonal architectures, and other modern automotive concepts. 

The guide gives you practical information about migrating away from fuses to IC switches, and collects information on recommended MOSFETs, gate drivers, and other products, as well as complementary components. Development tool info and other design resources are also provided. Download this solution guide to learn everything you need to know to get started with 48V powernet system development.
