STMicroelectronics Says Its GDU Boosts Motor-control Flexibility
- By MT Bureau
- April 22, 2022
STMicroelectronics has announced that its L9908 integrated automotive three-phase gate driver unit (GDU) operates in 12V, 24V, or 48V systems and has flexible input and output channels to fulfil numerous applications in conventional and hybrid/electric vehicles.
The company said in a statement that the dedicated source connections to the high-side and low-side FETs (field-effect transistors) of each half bridge let users configure the output channels independently to drive various types of loads.
Besides, six separate PWM (pulse-width modulation) input pins allow independent management of the pre-driver stages for different motor-control strategies, the release pointed out.
Claiming high accuracy, the company said that there are three differential current monitors for ground-referenced measurements and three channels for real-time phase-voltage monitoring. There is also a rich set of diagnostic and protection features.
The L9908 simplifies design, saves space, and enhances control of low-voltage fluid pumps, pumps and blowers in ventilation and cooling systems, and electronic seat controls. It can be also used in traction
inverters for mild-hybrid internal combustion engine (ICE) vehicles and 48V full-electric city cars, it said.
The L9908’s built-in diagnostics allow use in safety-related systems such as autonomous emergency braking (AEB) and advanced electronic power steering (EPS), simplifying certification according to ISO 26262.
The safety features include SPI-programmable dead-time insertion with shoot-through diagnostic and protection, open-load detection, and short-to-ground and short-to-battery diagnostics. There is also an
SPI-programmable temperature warning and SPI-readable junction-temperature measurement. Other diagnostics include ground-loss detection, over-voltage and under-voltage detection on the power supply pins and FET-driver supply, system-clock monitoring, SPI window watchdog, and a fault-status flag, the release added.
The flexibility to use the L9908 gate driver in single (12V), dual (24V), and 48V battery applications comes from its wide motor supply-voltage range, from 4.5V to 75V, with the ability to tolerate -14V to 95V on motor-connection pins. The on-chip logic is supplied from an internally generated 3.3V supply and digital I/Os are 3.3V- and 5V-compatible.
The company said L9908 is AEC-Q100 qualified and available now, in a thermally enhanced TQFP48 package. Pricing starts at USD 3.56 for orders of 1000 pieces. (MT)

Bengaluru-based electric two-wheeler maker Ather Energy has expanded its product line-up in Nepal with the introduction with the Ather Rizta e-scooter.
It was in November 2023 that Ather marked its entry in Nepal with the Ather 450 series and most recently introduced the 2025 Ather 450 in the region. Since then, it has established 9 Experience Centres and 6 Service Centres in the region along with 22 Ather Grid fast chargers.
Ravneet Singh Phokela, Chief Business Officer, Ather Energy, said, "Nepal was our first international market, and over the last two years, we have seen strong consumer interest and a very encouraging response to the Ather 450 series. To meet the growing demand, we have also steadily expanded our footprint across the country. With the launch of the Rizta, we are tapping into a new segment of family buyers who prioritise comfort and convenience in their everyday rides. We are hoping to see the same strong response for the Rizta as we’ve seen for the 450 series."

Swedish electric performance car brand Polestar has earned further acclaim for its innovative design philosophy. The Polestar 4 has secured the coveted Red Dot ‘Best of the Best’ award for 2025 in the Product Design category, celebrating its meticulous craftsmanship and bold design language. Both the Polestar 3 and Polestar 4 also received the Red Dot Label in the same category.
As one of the world's most prestigious design competitions, Red Dot acknowledged the Polestar 4's standout feature – its unconventional rear-windowless design – while praising its seamless fusion of coupe-like dynamism and SUV functionality. Additional design highlights include sleek frameless mirrors, distinctive dual-blade headlights and celestial-inspired ambient lighting, all contributing to its award-winning aesthetic. The ‘Best of the Best’ honour represents the highest Red Dot recognition, awarded only to groundbreaking designs that redefine industry benchmarks. An international jury of design experts rigorously assesses each entry through hands-on evaluation across multiple criteria.
This latest achievement builds on Polestar's strong Red Dot legacy, which includes prior "Best of the Best" wins for the Polestar 2, Brand of the Year distinction, and recognition for brand identity and design literature. These accolades reinforce Polestar's position as a leader in automotive design innovation.
“The Polestar 4 impressively succeeds in harmonising the technical complexity of such an advanced vehicle with design qualities such as simplicity and clarity,” remarked the jury.
Philipp Römers, Global Head of Design, Polestar, said, “This recognition is a testament to the dedication and passion of the Design Team here at Polestar. We are thrilled to see the work and commitment to distinctive design resonate with the jury.”

Exicom Tele-Systems Limited, a leading Indian manufacturer of EV charging and critical power solutions, has successfully raised around INR 2.59 billion through its recently concluded Rights Issue. The offering, which saw strong oversubscription, highlights sustained investor confidence and robust promoter support.
The Rights Issue, open from 15 to 30 July 2025, allotted 1,814,000 fully paid-up equity shares at INR 143 per share in a 3:20 ratio for eligible shareholders as of the record date 7 July 2025. Promoters demonstrated their commitment by subscribing to approximately INR 1.20 billion, reinforcing their belief in Exicom’s future growth.
Proceeds will primarily strengthen the company’s financial position by reducing debt, with a target debt-to-equity ratio of 1:4 by FY26. The funds will also support global expansion efforts, including enhancing market presence in the US, Europe and Australia through Tritium, alongside covering general corporate expenses. This successful capital raise positions Exicom to accelerate its EV charging and energy solutions business while driving long-term value for stakeholders.
Anant Nahata, Managing Director and CEO, Exicom, said, “We are grateful to our shareholders for their continued trust in Exicom. The capital raised will strengthen our balance sheet and support our expansion, particularly in international markets through Tritium. While Tritium’s turnaround is taking time, we are in advanced discussions for several large global high-power charger deals that we believe can help change the course of the company. We will see this fully play out starting FY27. Back home, we remain strongly optimistic about the India opportunity, driven by the steady growth in EV adoption across the country. Our Harmony Direct 2.0 continues to gain traction, with early momentum translating into a strong sales pipeline. Meanwhile, Spin Air home chargers are securing consistent wins with leading OEMs, reinforcing trust in our technology and execution."
Shiraz Khanna, Chief Financial Officer, Exicom, said, "This Rights Issue marks an important step in enhancing our financial health. The capital raised will enable us to significantly reduce debt and support sustainable growth while maintaining prudent capital discipline."
