ROHM Semiconductor Introduces Innovative Products and Concepts for Power & Energy Management

 

At the world’s leading show for electronics, electronica in Munich (Nov. 8-11, 2016/Hall A5-Booth 542), ROHM Semiconductor will showcase cutting-edge power management solutions for numerous applications in the automotive, industrial and residential/home area. Based on latest SiC and Si technologies, proprietary processing and packaging technologies, the introduced devices feature optimum efficiency and compactness, paving the way to cost and component reduction while delivering optimum performance. Combining ROHMs know-how in analog and digital power technology, they represent the most advanced developments of ROHM’s global R&D centers and joint designs with industry partnerships. All these products are manufactured in the company’s fully owned, vertically integrated production sites. Among others, key topics will be 3rd Gen SiC MOSFETs, SBDs, and Modules, LED-Drivers for exterior lighting, design kits for wireless power delivery and the technology partnership with Formula E-car developer Venturi.

Product Highlights: SiC Technology – 3rd Generation SiC MOSFETs, SiC SBDs and Modules

Utilising a proprietary double trench gate structure, ROHM’s new generation of SiC MOSFETs reduces ON-resistance by 50% and input capacitance by 35% in the same chip size compared with planar-type SiC MOSFETs. Optimum performance is achieved by combining exceedingly low loss with high-speed switching performance. As a result, efficiency during power conversion is improved, contributing to increased miniaturization, lighter weight, and greater energy savings.

The 3rd Gen of SiC Schottky Barrier Diodes (SBD) realize lowest VF and lowest IR within the entire temperature range among all SiC SBDs available in the market. In addition to this, they feature high surge current capability which is ideal for Power Supply applications. Adding to the recently announced TO220AC packages at 650V/6, 8 and 10A, ROHM will introduce D2pak (LPTL) packages solutions and lower currents products like 2A, 4A. ROHM’s new full SiC modules including a Chopper type module for converters leverage both Trench SiC MOSFETs and SiC SBDs.

Automotive Exterior LED Lighting

ROHM’s broad range of LED drivers is deployed in many automotive applications for interior as well as exterior lighting. High/Low Beam LED headlights, Matrix/Pixel LED dynamic front lights and dynamic sequential turn indicators mark the latest developments in exterior lighting. The company supplies LED drivers for rear lamps and Day Running Lights. Several application examples will demonstrate its benefits, i.e. a high beam/low beam demo, DRL example, a Matrix Headlamp and finally 2 matrix SW drivers for a sequential turn lamp system (a stand-alone and a matrix SW driver controlled by a MCU).

Medium Power Design Kit for Wireless Charging Applications in Cooperation with Würth Elektronik

Wireless power technology is garnering increased interest for being a convenient, reliable and safe way to recharge and power electronic devices like mobile phones at home, in the car and in the workplace. In this technology ROHM Semiconductor is a market leader with a full family of products targeting low and medium power Qi applications. To promote its Qi medium power-certified wireless power solutions, ROHM in collaboration with Würth Elektronik announces the availability of a design kit to demonstrate the advantages of wireless power charging. This gives engineers the opportunity to test and integrate wireless power solutions to their applications and it also accelerates adoption of the new technology in new and higher power areas. The kit is built according to the Wireless Power Consortium (WPC) Qi specification 1.2. as the next-generation standard for fast and safe inductive power transmission.

Technology Partnership with Venturi Formula E

Through the recently announced technical partnership with Venturi contesting the FIA “Formula E Series” for all-electric powertrain single-seater racing cars, ROHM shows the car and inverter as an application example to further contribute to advances in the area of e-mobility. Under this agreement, the Venturi e-car will be fitted with SiC devices. From season three, the vehicle will include ROHM-manufactured SiC SBDs within its inverter system. The goal is to significantly enhance the performance of the powertrain by leveraging SiC characteristics to improve energy efficiency and power density.
