ROHM Semiconductor Presents New High Voltage Isolated SiC Gate Drivers
ROHM Semiconductor presented its new BM6 family of 2,500 Vrms isolated SiC gate drivers facilitating low-power consumption and small designs. Due to their characteristics, these devices are ideal for the control of inverters and dc-dc converters for solar and automotive applications. Due to their electrical characteristics and high output voltage, they can drive both IGBTs and SiC MOSFETs. Together with ROHM’s SiC devices the new series guarantees a stable, high speed operation even in high power regions.
In order to develop on-chip transformer processes, ROHM utilized its proprietary microfabrication expertise. The unique design reduces the size to a compact SSOP-B20W package while eliminating the need for external parts, cutting the mounting area by approximately 50% compared to conventional products. Moreover, the original core-less transformer technology integrates an isolation function ensuring an isolation voltage of 2,500 Vrms.
In addition, multiple protection functions such as thermal shut-down and short circuit protection supporting desat function , fault and load control are included for high reliability, decreasing design effort while further contributing to miniaturization. A soft turn-off function deactivates the inverter in case of desaturation.
Samples are already available, mass production is scheduled for September 2012.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
