ROHM Co., Ltd. has developed an ultra-compact 1.8V to 5V rail-to-rail CMOS operational amplifier (op amp), the TLR377GYZ, which is the smallest in the industry as of August 1, 2024 (ROHM study). It is optimized for amplifying signals from sensors such as temperature, pressure, and flow rate as well as in smartphones, small IoT devices, and similar applications.
 
The size of smartphones and IoT devices continues to decrease, requiring smaller components. To accurately amplify small signals as needed in high-precision sensing, op amps must improve low input offset voltage and noise performance while continuing to shrink the form factor.
 
The TLR377GYZ successfully balances miniaturization with high accuracy (a challenge for conventional op amps) by further evolving proprietary circuit design, process, and packaging technologies cultivated over many years.
 
Op amps' input offset voltage and noise generation degrade amplification accuracy and can be suppressed by increasing the size of built-in transistors, but at the expense of miniaturization. In response, ROHM developed proprietary circuits which achieve a maximum offset voltage as low as 1mV without increasing the size of transistors with greatly reducing flicker noise, while ultra-low noise is achieved with an input equivalent noise voltage density of 12 nV/square root Hertz by optimizing the resistive components at the element level. Furthermore, the new product adopts a WLCSP (Wafer Level Chip Scale Package) with a ball pitch of just 0.3mm, utilizing original packaging technology. This reduces size by approximately 69% compared to conventional products and 46% over existing compact products.

The IC-mounted conversion board that can replace SSOP6 packages is also offered to support replacement considerations and initial evaluation. Both the new product and conversion board are available for purchase through online distributors. Additionally, the high-accuracy SPICE model, called ROHM Real Model, is available on ROHM's website for verification simulations.

- Industry-leading* Power Density Achieved by Integrating 4th Generation SiC MOSFETs in Compact Package -
 
ROHM Co., Ltd. has developed four models as part of the TRCDRIVE pack (TM) series with 2-in-1 SiC molded modules (two of 750V-rated: BSTxxxD08P4A1x4, two of 1,200V-rated: BSTxxxD12P4A1x1) optimized for xEV (electric vehicles) traction inverters. TRCDRIVE pack (TM) supports up to 300kW and features high-power-density and a unique terminal configuration, helping solve the key challenges of traction inverters in terms of miniaturization, higher efficiency, and fewer person-hours.
 
As the electrification of cars rapidly advances towards achieving a decarbonized society, the development of electric powertrain systems that are more efficient, compact, and lightweight is currently progressing. However, for SiC power devices that are attracting attention as key components, achieving low loss in a small size has been a difficult challenge. ROHM solves these issues inside powertrains with its TRCDRIVE pack (TM).
 
A trademark brand for ROHM SiC molded type modules developed specifically for traction inverter drive applications, TRCDRIVE pack (TM) reduces size by utilizing a unique structure that maximizes heat dissipation area. On top, ROHM’s 4th Generation SiC MOSFETs with low ON resistance are built in, resulting in an industry-leading power density level 1.5 times higher than that of general SiC molded modules while greatly contributing to the miniaturization of inverters for xEVs.
 
The modules are also equipped with control signal terminals using press fit pins enabling easy connection by simply pushing the gate driver board from the top, reducing installation time considerably. In addition, low inductance (5.7nH) is achieved by maximizing the current path and utilizing a two-layer bus-bar structure for the main wiring, contributing to lower losses during switching.

ROHM Develops Automotive Primary LDOs: Leveraging Original QuiCur(TM) Technology to Achieve Industry-Leading Load Response Characteristics
-Ensuring Stable Output in Automotive Applications with High Input Voltage and Significant Load Jumps-
 
ROHM Co., Ltd. has developed 45V-rated 500mA-output primary LDO regulators: BD9xxM5-C. These devices are suitable for supplying power to automotive electronic components such as ECUs that operate from vehicle batteries.
 
BD9xxM5-C: https://www.rohm.com/products/power-management/linear-regulators/single-output-ldo-regulators?page=1&PS_ProductSeries=BD9xxM5%20series&PS_CommonStandard=AEC-Q100%20(Automotive%20Grade)#parametricSearch

In recent years, the number of onboard power supply systems and functions continues to grow as electrification in the automotive industry progresses. This increases demand for primary LDOs that can directly step down the battery voltage to MCUs and other components used in ECUs. However, the energy supplied by the vehicle’s lead-acid battery is often subject to sudden voltage fluctuations, which primary LDOs are required to provide with excellent line-transient response in these conditions.
 
At the same time, ECUs and other downstream devices often experience load current variations during operation, which also demand excellent load-transient response characteristics. A high-frequency response is essential for fast output voltage recovery, but it has been difficult to provide sufficient phase margin at the same time to ensure stable operation. In response, ROHM developed a novel solution that addresses these challenges.
 
The BD9xxM5-C incorporates original QuiCur(TM) high-speed load response technology that delivers excellent response characteristics to load current fluctuations. For example, the LDO can maintain output to within 100mV of set voltage even as the load changes between 0 and 500mA in 1-microsecond (rise-time/fall-time). Furthermore, low 9.5-microampere (typ.) current consumption contributes to lower power consumption in automotive applications. These new products will be available in four packages, ranging from the compact HTSOP-J8 to the high heat dissipation TO252 and HRP5 types. This allows users to select the most suitable package for each use case.
 
ROHM will continue to improve reliability while reducing power consumption in automotive applications by developing products utilizing its strengths in analog and other technologies.

■CMストーリー
「electric landscape」篇（15秒・30秒）
山林や田園の自然風景、町や都市の街並みの風景と、半導体などが作り出す電子回路基板の風景をリンクさせ、「人が自然の一部だとすれば、人が創り出すものもまた、自然の一部にほかならない」という世界観を表現しています。また、音楽にOfficial髭男dismの「115万キロのフィルム」を使用することで、より情緒的にCMのメッセージを表現しています。
 

 
■CM制作背景
◇CMのコンセプト
いま世界中で、自然環境が、人の暮らしが、大きく変化しています。
人間の創り出すテクノロジーは、急速に進歩し、それは地球の自然や環境を壊しかねないほど強くなりました。だからこそ、私たちは、これまで以上に何をつくり、それを使ってどんな世界を作り出していくかということを、注意深く、真剣に考えて行かなければならないと思います。
ロームは、自動車や産業機器、家電・通信機器まで、地球上のあらゆる電子機器の中で働く「半導体」をつくっている会社です。最先端のテクノロジーを提供する会社だからこそ、質の高い製品を作るだけでなく、その先に、どうすれば豊かな世界を作っていけるかを真剣に考えていかなければならない。そんなロームの想いを伝えることが、このCMのコンセプトです。
 
◇「Official髭男dism」のタイアップと「115万キロのフィルム」の選定理由
ロームは、40年以上前から、オーディオ機器に向けた電子部品・半導体の開発にも取り組んでおり、音楽を通じて豊かな文化を育んでいくための様々な音楽文化支援活動も行っています。ロームにとって、音楽は非常に大切な文化であり、人々の心を動かす音楽を次々と送り出している「Official髭男dism」の活動には深く共感します。また、今回のCMで伝えたかったことは、ロームが、小さな電子部品に、大きな夢や未来への熱い想いを託しているということ。そして、「Official髭男dism」とタイアップし、あえてインディーズ時代の「115万キロのフィルム」を選定したのは、そこにまっすぐに表現された人間愛や熱い想いがCMのメッセージと響き合い、情緒的な強さを引き出してくれると感じたからです。結果として、映像やナレーションの奥に秘められたエモーションが伝わるCMになったと考えています。
 
◇制作にあたり、こだわったポイント
半導体が活躍するミクロの風景と、私たちが住む街のようなマクロの風景は、驚くほど似ている。その驚きが、見る人をこのCMに引き込んでいく入り口になっています。その驚きを見る人の中に、いかに引き起こせるかが、最もこだわったポイントです。
