eGaN® FETs and ICs for Medical Technology

Advances in semiconductor technology are resulting in advances in the field of medicine. The high frequency switching speed and small size of GaN are enabling applications such as wireless power transfer. Today, enabled by the emergence of GaN technology, there are major leaps forward in activities such as medical imaging, diagnostic techniques, and human implantable devices. For high voltage lateral GaN transistors, all of the electrical connections are located on the same side of the die, allowing for the elimination of complex, performance limiting two-sided packaging common in vertical Si power MOSFETs. Chip-scale packaging is a more efficient form of packaging that reduces the resistance, inductance, size, thermal impedance, and cost of power transistors, enabling unmatched in-circuit performance.

Benefits

Wireless Power for Implantable Devices


On-patient wireless power applications

EPC2107 100 V, 0.5 A Die size: 1.35 mm x 1.35 mm
eGaN FETs switching speed enables wireless power transfer for implanted devices which eliminates the need for through-skin cables, reducing the mortality rate while making it possible for patients to maintain a quality of life

Imaging Equipment and Diagnostics


Image resolution is critical to MRI scanners
eGaN FETs provide improved scanning speed allowing more coils to be employed, thus reducing distortion of the magnetic field and decreasing overall power consumption for imaging equipment

Non-invasive “colonoscopy pill” from Check-Cap Ltd

EPC2012C 200 V, 22 A Die size: 1.7 mm x 0.9 mm
eGaN FETs high frequency switching increases performance of X-Ray based diagnostic systems and the FET’s extremely small chipscale packaging enables high energy density

Robots


EPC2039 80 V, 50 A Die size: 1.35 mm x 1.35 mm
GaN’s small size, thermal efficiency and high frequency switching contribute to high resolution motor control for medical robotics
