xEV
Minimizing energy consumption is important to extend the range of electric vehicles.
ROHM's SiC power semiconductors help to improve xEV performance by enhancing efficiency, reducing size, and supporting higher voltages in a variety of applications, including main inverters, onboard chargers, and DC-DC converters.
ROHM’s Approach to Functional Safety

ROHM has established dedicated lines for automotive products while developing products that comply with quality management system (IATF 16949) and electronic component reliability (AEC-Q100/101/200) standards.
In 2015, we began establishing an ISO 26262 process to address functional safety, and in March 2018 acquired ISO 26262 development process certification from 3rd party certification body TÜV Rheinland, demonstrating our proactive commitment to improving automotive safety.
Reference Design

ROHM provides a system-level evaluation board (solution board) that combines ROHM's IC and discrete products. We have already solved not only the characteristics of individual products but also the problems that may occur when combining them to build a system, thus contributing significantly to the reduction of development time for our customers.
Topology Selection
When designing power supply circuits, it is necessary to select a circuit configuration (topology) that meets the required specifications, as the input/output voltages, power, isolation, and other factors will vary depending on the application. Selection of the optimal components will also differ based on the topology. Selecting the wrong components can lead to a failure to meet the required specifications, necessitating a complete redesign of the circuit. ROHM’s topology selection page guides users in selecting the optimal devices for various topologies.
ROHM Solution Simulator

ROHM Solution Simulator is a new web-based electronic circuit simulation tool that can carry out a variety of simulations, from initial development that involves component selection and individual device verification to the system-level verification stage. This makes it possible to quickly and easily implement complete circuit verification of ROHM power devices (i.e. SiC) and ICs (e.g. driver and power supply ICs), in simulation circuits under close to actual conditions, significantly reducing application development efforts.
