ROHM's BD70522GUL is an ultra-low-power DC/DC converter with integrated MOSFETs, which meets the requirements of the IoT market for a long battery life of up to ten years with a single coin battery due to its low power consumption of only 180nA. In recent years, the number of battery-powered devices such as smartphones and wearables for IoT has risen sharply.

Since Season 3 (2016/2017), ROHM Semiconductor has been official technology partner of the VENTURI Formula E team. ROHM bring its SiC (Silicon carbide) power devices, which it claims to be a cutting edge technology for e-mobility, to the race track to increase the effectiveness of the power electronics system in the VENTURI Formula E cars. Formula E is the leading racing event for electric vehicles.

  With the introduction of its newly established European 'Power Lab', ROHM Semiconductor has demonstrated the deployment of its global strategy on the power semiconductor market in Europe. The company's mission statement has been 'Quality is our top priority' for 60 years, and the new power electronics lab confirms this high standard.

  A buck-boost DC/DC converter with built-in MOSFET has been developed by ROHM, featuring what it claims to be the lowest current consumption in the industry. As a result, it is suitable for electronic devices powered by batteries such as electronic dictionaries, remote controls for home appliances, and items such as toys, and other portable electronic devices.

A significantly more compact version of ROHM's PSR series has been introduced. The PSR100 series ultra-low ohmic shunt resistors have a high-power capability and are suited to current measurement in automotive and industrial applications. The new shunt resistors, which are based on a high-performance metal alloy as the resistive element, feature temperature coefficients (TCR) from ±50 to ±150ppm.

  ROHM has recently announced the availability of its dual-input boost-buck charging ICs that support 1-4 battery cells for notebook PCs, smartphones, and power banks and is fully compatible with the the latest charging technologies such as wireless and USB Power Delivery (USBPD).

The VENTURI Formula E team in the FIA Formula E 2017-2018 (season four) was provided with full SiC power modules from ROHM. This module will support further improvements in the car’s performance under racing conditions. ROHM became VENTURI’s official technology partner in season 3, and provides what the company claims to be the world’s most advanced SiC power devices used in the inverter, which is the core of the ...

Suitable for current detection in high-power applications in the automotive, industrial and large-scale consumer electronics sectors, ROHM has announced the development and mass production of high-power low-ohmic shunt resistors of the GMR100 series. The new shunt resistors are characterised by a high rated power of 3W and a resistance range from 5-220mΩ. Their resistance tolerance is specified with F (±1%). The temperature coefficie...

  A new DC/DC converter from ROHM Semiconductor has been announced named BD9V100MUF-C. It features a built-in MOSFET that can generate output voltages of just 3.3 or 5V (minimum 2.5V) from input voltages up to 60V at a switching frequency of 2MHz.

With its BA8290xYxx-C series, ROHM is offering automotive-grade op-amps featuring superior noise immunity. The output voltage fluctuations are suppressed in all frequency bands to less than ±1%, compared to ±3.5% to ±10% with conventional products. This allows, for example, sensor signals to be amplified without the need for noise countermeasures, which significantly reduces design load and contributes to greater reliability.

  ROHM Group company LAPIS Semiconductor has recently announced the availability of an RF LSI optimized for LPWA (Low Power Wide Area), which is expected to usher in a new area of wireless IoT communication.

Designed to connect to information and peripheral devices using the new Type-C connector, ROHM has announced the availability of USB Power Delivery (USBPD) compatible transmitter/receiver evaluation boards. Recent years have seen a greater demand to reduce industrial waste in many regions, including Europe, for example by utilising or developing universal connectors and chargers for a variety of electronic devices that can be used world...

ROHM Group company Kionix has added embedded functionality to its line of high-performance accelerometers. The new KX126 tri-axis accelerometer integrates a step detector and step counter. According to Nader Sadrzadeh, Kionix’s CEO, “As the applications for sensors grow, we look for use cases that become widespread enough to warrant embedding algorithms and functionality directly into our sensors.

ROHM Semiconductor and A*STAR’s Institute of Microelectronics (IME), a renowned research institute under the Agency for Science, Technology and Research (A*STAR), recently announced the joint development of an artificial intelligence (AI) chip to boost efficiency in predictive maintenance for smart factories.

PCIM Europe 2017: A new generation of IGBTs, announced by Rohm, use advanced cell structure for high circuit efficiency and soft switching.They have been designed for soft, efficient switching in industrial applications and home appliances.

ROHM has recently announced the availability of a sound processor capable of high resolution audio playback that performs volume adjustment and audio mixing for car audio and navigation systems requiring high sound quality. In recent years the proliferation of quieter cabins and higher resolution sound sources resulting from the introduction of EVs and PHVs has increased demand for more accurate audio representation – even in the car a...

ROHM Semiconductor will debut its latest power product designs at PCIM, the leading trade fair for Power Electronics, Intelligent Motion and Energy Management in Nuremberg, from May 16 – 18, 2017 (Hall 9, Booth 316). Energy savings and reduced system costs in all kinds of systems are heavily influenced by choosing the right power device.

Believed to be the first DC/DC converter that is capable of DC fan motor speed control, the BD9227F reduces real estate demands (Visit PCIM Europe 2017 Stand 9-316). Designed to benefit integrated design, with a 75% reduction in mounting area compared with that of discrete configurations, the buck DC/DC converter is optimised for DC fan motor power supplies used in applications such as cold air circulation in refrigerators, says Rohm.
