Maximize efficiency with a combo-box architecture

Integrating the traction inverter, DC/DC converter and on-board charger can reduce vehicle weight, lower overall costs and achieve higher power density, helping enable electric vehicles for the masses. Integrating systems brings new technical challenges such as complex magnetic integration and the need for a more sophisticated control algorithm. With products such as C2000™ microcontrollers that help simplify control algorithm challenges and our high-voltage isolation portfolio, featuring products such as isolated gate drivers that enable effective integration, we have the products, resources and expertise to help achieve your design goals, regardless of the level of integration you seek.

Use this high-power-density, high-efficiency totem-pole PFC design to power on-board charger systems up to 6.6 kW with 98.6% efficiency.

Reliable, efficient battery management systems (BMS)

The battery is the most expensive component of an electric vehicle. As more vehicles become electrified, you need highly accurate, reliable battery monitoring and protection in order to meet the highest levels of functional safety. Accurate monitoring also enables more efficient battery use, resulting in either higher mileage per charge or maintained mileage with reduced battery size and a resulting decrease in cost. Our battery management integrated circuits and systems resources can help you maximize the safety, efficiency and power density of your high-voltage 12-V, 48-V and wireless battery management system design challenges.

Unlock the benefits of 48-V systems

Electrification increases power demands, and 12- to 48-V and 48-V to high-voltage architectures increase the available power to meet those demands. Introducing a 48-V power supply, however, creates new and challenging design requirements, particularly the accurate monitoring and protection of the 48-V battery and achieving Automotive Safety Integrity Level (ASIL)-D certification while managing cost at scale. Our analog and embedded processing products are up for the challenge. With wide-input-voltage DC/DC converters and brushless DC motor drivers that enable safety at high levels of power density; a portfolio of highly accurate sensing products; and a broad selection of high-performance, low-power microcontrollers that simplify the development process, we can help solve all of your 48-V design challenges. Explore our 48-V battery management system, 48-V to 12-V bidirectional DC/DC converter and starter/generator resources.
