Integrated Grade 0 BLDC motor driver shrinks 48-V motor-drive systems as much as 30% in mild hybrid electric vehicles

To help decrease greenhouse gas emissions globally, automobile manufacturers are increasing the production of MHEVs, which use 48-V motor-drive systems to help reduce emissions from a vehicle’s internal combustion engine. The TI Functional Safety-Compliant DRV3255-Q1 allows manufacturers to design a motor-drive system to help enable MHEV systems up to ASIL D, supplying as much as 30 kW of motor power which can improve the response time of a 48-V motor-drive system in heavy vehicles.

“A 48-V system is a step-change that original equipment manufacturers [OEMs] can implement to meet goals around reducing emissions, while also adding power for advanced driver-assistance system features and managing power-hungry loads such as the heating, ventilation and air conditioning system,” said Asif Anwar, director of the powertrain, body, chassis and safety service at Strategy Analytics. “Combining leading-edge performance characteristics with functional safety and Grade 0 translates to real-world, system-level operational benefits that will help OEMs achieve these goals.”
