At the upcoming electronica 2018, 13th to 16th November, 2018, in Munich, ROHM Semiconductor will be exhibiting. At its exhibition booth in hall C3, stand 512, the company will present new solutions for power and energy management in the automotive and industrial sectors as well as its commitment to Formula E.
ROHM has announced that it has received certification for the development process under the ISO 26262 functional safety standard for automotive products by third-party certification authority TÜV Rheinland in Germany. This certification allows ROHM to develop automotive-grade devices that achieve the highest level of safety (ASIL-D).
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.
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.
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 electric vehicle powertrain.
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 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 audio sector.
Chipsets designed to drive and control automotive LCDs have been announced by ROHM and LAPIS Semiconductor. These include larger high resolution monitors used for navigation and the instrument cluster.
