ROHM has plans to build a new facility at ROHM Integrated Systems (Thailand) (RIST) to address the increasing demand for expanding the post processing production capability of LSIs. The project, which is currently in the design phase, is scheduled to begin in December 2014 and be completed by December 2015. 

Designed for MCUs in a variety of automotive systems, including EVs and HEVs, the BD39001EKV-C power supply has been released by ROHM. Ensuring stable voltage supply, even when the battery voltage drops after idling stop, the device utilises a proprietary boost-buck switching method.

  As the industry pushes forward to realise SiC’s full potential, Jochen Hüskens, Rohm Semiconductor, argues that the next generation of SiC power devices is well-positioned to enable new high-volume applications such as EVs and solid state transformers.

Achieving simple audio playback via connection to a speaker, LAPIS Semiconductor, a ROHM Group Company, has introduced a low power MCU. The ML610Q304 integrates an 8-bit low power MCU core, speech synthesis circuit, high efficiency Class-D speaker amplifier, non-volatile memory and oscillator circuit on a single chip.

To meet the demand for high-performing, compact power supply applications, ROHM has introduced the BD9G101G and BU9000xGWZ DC/DC converters. The BD9G101G converter provides a wide operating voltage range of 6-42V, with an extended operating temperature range of -40 to 105°C. In a SOT23 (SSOP6) package which measures only 2.9x2.8x1.25mm, the converter also allows designers to reduce space by more than 20%.&nb...

Low-ohmic chip resistors, optimised for current detection applications in compact equipment, have been developed by ROHM Semiconductor. The UCR006 series of ultra-compact (0.6x0.3mm) thick-film chip resistors is offered in resistances as low as 100mΩ, providing greater energy savings.

Based on innovative proprietary packaging and manufacturing technologies, ROHM have introduced a family of devices which they claim are the smallest electronic components in the industry. The RASMID (ROHM Advanced Smart Micro Device) families include ultra-compact chip resistors in 03015 (0.3 × 0.15mm) size as well as Schottky barrier diodes in 0402 (0.4 × 0.2mm) size.
