Toshiba Electronics Europe GmbH launched two products for brushless DC (BLDC) motor drive applications including fan motors, ventilation fan, air conditioners, air cleaners, and pumps.
Each of the intelligent power devices (IPD) incorporate 600V-rated IGBTs and a matched gate driver as a one-chip solution in a single compact package. The output DC current (IOUT) rating of the TPD4163F is 1A while the TPD4164F is rated at 2A.
The two devices (TPD4163F and TPD4164F) have an IGBT saturation voltage (VCEsat) of 2.6V and 3.0V respectively, while the Diode forward voltage (VF) is 2.0V and 2.5V.
Both devices are housed in a miniature surface mount HSSOP31 package. With dimensions of just 17.5mm x 11.93mm x 2.2mm, the PCB footprint is reduced by around 63% when compared with Toshiba’s existing DIP26 package products. This makes a significant contribution to reducing the space required for motor drive circuit boards.
In addition, in geographic regions where the power supply is unstable, the supply voltage may fluctuate significantly. Therefore, to improve reliability, the supply voltage rating (VBB)has been increased from 500V to 600V to introduce more design margin.
To support the new devices, Toshiba has developed a reference design for BLDC sensorless brushless DC motor drive utilizing the new TPD4164F and a microcontroller TMPM374FWUG.
Toshiba will continue to expand their product lineup with various packages and improved characteristics, contributing to customers’ design flexibility and carbon neutrality through energy-saving motor control.
Volume production shipments of both new devices (and the reference design board) start today.

Shin-Etsu Chemical Co., Ltd. has determined that QST® (Qromis Substrate Technology) substrate is an essential material for the social implementation of high-performance, energy-efficient GaN (gallium nitride) power devices, and the company will promote the development and launching on the market of these products.
Since QST® substrate is designed to have the same coefficient of thermal expansion (CTE) as GaN, it enables suppression of warpage and cracking of the GaN epitaxial layer and resultant large-diameter, high-quality thick GaN epitaxial growth. Taking advantage of these characteristics, it is expected to be applied to power devices and RF devices (5G and beyond 5G), which have been rapidly growing in recent years, as well as in such areas as MicroLED growth for MicroLED displays.
In addition to sales of QST® substrates, Shin-Etsu Chemical will also sell GaN grown QST® substrates upon customer request. We currently have a line-up of 6″ and 8″ diameter substrates, and we are working on 12″ diameter substrates. Since 2021, for each respective application for power devices, RF devices and LEDs, sample evaluation and device development are continuing with numerous customers in Japan and globally. Especially for power devices, continuous evaluation is underway for devices in the wide range of 650V to 1800V.
So far, Shin-Etsu Chemical has repeatedly made many improvements with regard to its QST® substrates. One example is the significant improvement in lowering defects originating from the bonding process, which has enabled the supply of high-quality QST® substrates. In addition, for the thicker GaN films that many of our customers have requested, we have promoted the provision of template substrates with optimized buffer layers, which enables our customers to realize stable epitaxial growth of more than 10 μm thickness. Furthermore, various successful results have been produced and reported on, including the achievement of thick-film GaN growth exceeding 20 μm using QST® substrates and the achievement of 1800V breakdown voltage in power devices.
Moreover, Shin-Etsu Chemical and Oki Electric Industry Co., Ltd. have jointly succeeded in developing a technology to exfoliate GaN from QST® substrates and bond it to substrates made of different materials using Crystal Film Bonding (CFB) technology. Until now, most GaN power devices have been lateral devices, but CFB technology takes advantage of the characteristics of QST® substrates to realize vertical power devices that can control large currents by exfoliating a thick layer of high-quality GaN from an insulating QST® substrate (see figure below).
To customers who manufacture GaN devices, Shin-Etsu Chemical will provide QST® substrates or GaN grown QST® substrates and Oki Electric Industry will provide its CFB technology through partnering or licensing. In this way, the two companies hope to contribute to the advancement of vertical power devices.
Based on these development results and also based on business situation inquiries from customers, Shin-Etsu Chemical will continue to increase production to meet customer demand.
Shin-Etsu Chemical will contribute to the realization of a sustainable society that can use energy efficiently by further promoting the social implementation of GaN devices that have characteristics that are absolutely essential for the future society.

McLaren Applied has launched IPG5-x, a highly flexible 800V Silicon Carbide (SiC) inverter that can be integrated into Electric Drive Units (EDUs). Targeting growing OEM demand for high-performing, integrated EDUs that save space and cost, the British engineering and technology pioneer has developed IPG5-x to work with a variety of motors and transmissions – especially in performance applications.
IPG5-x is an adaptation of McLaren Applied’s current award-winning 800V SiC inverter, IPG5. IPG5-x will coexist alongside the standalone IPG5, with application depending on customer need. The ‘x’ suffix was chosen because IPG5-x is a product designed for collaboration with Tier 1 and OEM partners looking to bring EDU products to market quickly and cost effectively. McLaren Applied is in discussions with several OEMs and Tier 1 suppliers, and is working with transmission provider TREMEC to jointly develop an integrated EDU for their first customer vehicle application.
“In our discussions with customers and partners, it’s become clear that OEMs are increasingly looking for the option to source integrated EDUs that save space, cost and speed up development time,” commented Paolo Bargiacchi, Head of Product, Automotive at McLaren Applied. “We’ve developed the IPG5-x to be highly flexible, so it’s ready to be integrated within any combination of motor and transmission. It carries over all of our standalone IPG5’s qualities – peak efficiencies over 99%, continuously variable switching and fine motor control – building on the maturity of that product.”
Derived from decades of innovation in top tier automotive and motorsports, McLaren Applied’s IPG5-x offers best-in-class fine motor control and high efficiency through continuously variable switching frequencies; maximising the advantages of SiC semiconductors.
The IPG5-x forms a step forward in what the automotive team at McLaren Applied describes as the ‘waves of electrification’. The first wave involved early pioneers of technology, the second wave is denoted by the breakthrough of EVs to the mainstream. The third wave is efficiency and will see inverter technology rapidly adopt SiC semiconductors, especially in 800V architectures, enabling vehicles to achieve longer range where efficient power electronics are key.
Bargiacchi added: “The immediate focus must be on achieving greater drivetrain efficiency and cost reduction, which you can do through a product like IPG5-x. The competitive landscape is ramping up significantly now that all manufacturers have established their product entry points.
“Models based on dedicated 800V SiC architectures are leading the way, driving a virtuous cycle: an efficient drivetrain inherently has a smaller battery, which makes the vehicle cheaper, lighter and easier to control, and offers a smaller embedded and operating carbon footprint. It also increases range and speeds up charge times, building trust in the technology.”
As competition increases, we will enter the fourth wave, where OEMs will need to differentiate the customer experience their products deliver. In anticipation of this change, McLaren Applied has developed advanced motor control software in both IPG5 and IPG5-x that enables a variety of features ranging from improved refinement through to a more engaging drive.
