Case Studies

The DISPERSE project enabled MinDCet to develop a methodology for designing low-power, MRI-compatible ASICs. A hearing-aid implant ASIC was successfully tested in 1.5T and 3T MRI environments, demonstrating reduced interference under strict implant power constraints. As a result, MinDCet established a “mag-hard” design approach for ASICs tolerant to strong magnetic and RF fields, applicable to biomedical implants and other harsh environments.

Gallium Nitride (GaN) power ICs are transforming industries. GaN modules provide compact and high-performance solutions with reduced losses and improved power density. This makes them ideal for demanding applications such as downhole drilling, electric vehicles, aviation, and industrial power systems. As part of the ALL2GaN Project, we developed a monolithic GaN IC module optimized for use in buck converters and active rectifiers.

Late-stage surprises in magnetic component behavior can potentially derail even the most rigorously simulated designs. When an overheating inductor threatened delivery timelines for Thales Alenia Space Belgium, a rapid and application-accurate solution was essential. MinDCet deployed its patented MADMIX system to quickly characterize multiple components' power losses. The result: high-confidence design decisions and avoided redesign cycles, while presenting a compelling case for integrating advanced inductor measurements early in development.

Geostationary or low-orbit, communication satellites have a power-hungry payload and a limited overall capability to support their weight and power. This knowledge, combined with the decades of experience from TaS-be power supplies, has resulted in the development of a Rad-hard GaN gate-driver ASIC. This 200V state-of-the-art ASIC is unique in it’s abilities and enables TaS-be to both tackle increasing life-time demands of geo-stat satellites (18 years) and low-cost / high-quality demands of new-space.

Jet fuel injection is a critical parameter that needs tight control and can lead to a leap in reducing the consumption. Tight control means fuel-valve drive and control electronics that are by definition close to the jet engine itself. High ambient temperatures (200°C) makes this a very hostile and challenging environment for the electronics. Inspired by these challenges MinDCet has provided a solution to General Electric (GE), a leading player in this field, in the form of a high-temperature ASIC.

Originating from the high-end RC toys world (cars, planes, boats…), Brushless-DC motors (BLDC) are replacing older brushed DC motors in various industries. Obvious advantages are a longer lifetime and higher efficiency, but motor control is more complicated. MinDCet was the partner of choice for Melexis to implement a monolithic 40V / 3A peak sensor-less BLDC motor drivers. By integrating the sensing, controlling, gate-driver and power-stages into a single chip, a significant reduction in bill-of-material and cost was achieved.
