Gallium nitride (GaN) power devices have been in production for over 10 years and, beyond just performance and cost improvements, the most significant opportunity for GaN technology to impact the power conversion market comes from the intrinsic ability to integrate multiple devices on the same substrate. This capability will allow monolithic power systems to be designed on a single chip in a more straightforward, higher efficiency, and more cost-effective way.

The ultra-fast transition EPC2034C eGaN^® FETs used on the EPC9150 enables high current pulses up to 220 A and pulse widths under 3 ns, thus allowing a lidar system to see farther, faster, and better.

EL SEGUNDO, Calif.— March 2021 — Efficient Power Conversion  (EPC) announces the availability of the EPC9150, a 200 V, high current, pulsed-laser diode driver demonstration board. In a lidar system, used to create 3-D maps for autonomous vehicle applications, speed and accuracy of object detection is critical. As demonstrated by this board, the rapid transition capability of the EPC2034C eGaN FETs provide power pulses to drive the laser diodes, VCSELs or LEDs up to ten times faster than an equivalent MOSFET and in a small fraction of the area, energy, and cost. Thus, enhancing the overall performance, including accuracy, precision, and processing speed as well as the price of a lidar system.

New family of laser driver IC products will enable faster adoption and increased ubiquity of ToF solutions across a wider array of end-user applications.

Efficient Power Conversion (EPC) expands AEC Q101 product family with the addition of the EPC2219, 65 V gallium nitride transistor with integrated reverse gate clamp diode optimized for high resolution lidar systems.

EL SEGUNDO, Calif.— March 2021 — EPC announces successful AEC Q101 qualification of the 65 V EPC2219 designed for lidar systems in the automotive industry and other harsh environments. 

Enhancement-mode gallium nitride (eGaN) FETs have demonstrated excellent thermomechanical reliability in actual operation in the field or when tested according to AEC or JEDEC standards. This is because of the inherent simplicity of the “package,” the lack of wire bonds, dissimilar materials, or mold compound. Recently, an extensive study of underfill products was conducted to experimentally generate lifetime predictions. A finite element analysis at the end of this section explains the experimental results and generates guidelines for selection of underfill based on key material properties.

In last month’s Safety & Compliance column in How2Power, “WBG Semiconductors Pose Safety And EMI Challenges In Motor Drive Applications,”[1]Kevin Parmenter made some assertions about the difficulties of using SiC, and to a lesser extent GaN, power semiconductors in large motor-drive applications. This commentary is a response to that article, showing that GaN can be a game changer in low-voltage integrated motors.
