Infineon Technologies AG announced two new CoolGaN™ product technologies, CoolGaN bidirectional switch (BDS) and CoolGaN Smart Sense. CoolGaN BDS provides exceptional soft- and hard-switching behavior, with bidirectional switches available at 40 V, 650 V and 850 V. Target Applications of this family include mobile device USB ports, battery management systems, inverters, and rectifiers.
The CoolGaN Smart Sense products feature lossless current sensing, simplifying design and further reducing power losses, as well as transistor switch functions integrated into one package. They are ideal for usage in consumer USB-C chargers and adapters.
The CoolGaN BDS high voltage will be available at 650 V and 850 V and feature a true normally-off monolithic bi-directional switch with four modes of operation. Based on the gate injection transistor (GIT) technology, the devices have two separate gates with substrate terminal and independent isolated control. They utilize the same drift region to block voltages in both directions with outstanding performance under repetitive short-circuit conditions.
Applications can benefit by using one BDS instead of four conventional transistors, resulting in higher efficiency, density, and reliability. Furthermore, significant cost savings are achieved. The devices optimize performance in the replacement of back-to-back switches in single-phase H4 PFC and HERIC inverters and three-phase Vienna rectifiers. Additional implementations include single-stage AC power conversion in AC/DC or DC/AC topologies.
The CoolGaN BDS 40 V is a normally-off, monolithic bi-directional switch based on Infineon’s in-house Schottky Gate GaN technology. It can block voltages in both directions, and through a single-gate and common-source design, it is optimized to replace back-to-back MOSFETs used as disconnect switches in battery-powered consumer products. The first 40 V CoolGaN BDS product has a 6 mΩ R DS(on), with a range of products to follow. Benefits of using 40 V GaN BDS vs. back-to-back Si FETs include 50 – 75 percent PCB area savings and a reduction of power losses by more than 50 percent, all at a lower cost.
The CoolGaN Smart Sense products feature 2 kV electrostatic discharge withstand and can connect to controller current sense for peak current control and overcurrent protection. The current sense response time is ~200 ns, which is equal or less than common controller blanking time for ultimate compatibility.
Implementing the devices results in increased efficiency and cost savings. At a higher R DSs(on) of e.g. 350 mΩ, the CoolGaN Smart Sense products offer similar efficiency and thermal performance at lower cost compared to traditional 150mΩ GaN transistors. Moreover, the devices are footprint compatible to Infineon’s transistor-only CoolGaN package, eliminating the need for layout rework and PCB respin, and further facilitating design with Infineon’s GaN devices.
Engineering samples of the CoolGaN BDS 40 V are available now for 6 mΩ and will follow in Q3 2024 for 4 mΩ and 9 mΩ. Samples of the CoolGaN BDS 650 V will be available in Q4 2024, and 850 V will follow early 2025. CoolGaN Smart Sense samples will be available in August 2024.

NXP Semiconductors N.V. announced a collaboration with ZF Friedrichshafen AG, a global leader in e-mobility, on next-generation SiC-based traction inverter solutions for electric vehicles (EVs). By leveraging NXP’s advanced GD316x high-voltage (HV) isolated gate drivers, the solutions are designed to accelerate the adoption of 800-V and SiC power devices. Safe, efficient and higher performance traction inverters enabled by the GD316x product family can be designed to extend EV range and reduce the number of charging stops while lowering system level costs for OEMs.
The collaboration between ZF and NXP is a significant step towards accelerating the electrification of the automotive industry, and creating more safe, sustainable, and energy-efficient EVs for the future.
“We look forward to working with NXP to raise the bar for the capabilities and performance of our 800-V traction inverter solutions, which will help us achieve our goals of reducing emissions and promoting sustainability,” said Dr. Carsten Götte, SVP Electrified Powertrain Technology at ZF. “The combination of ZF’s expertise in motor control and power electronics with NXP’s GD316x gate driver family enables us to provide our latest SiC-based traction inverters with higher power and volume density, efficiency and differentiation, and provide our customers with significant safety, efficiency, range and performance improvements.”
Traction inverters are a critical component of an EV’s electric powertrain, converting DC voltage from the battery into a time-varying AC voltage, which drives the vehicle’s motor. As traction inverters now migrate to SiC-based designs, the SiC power devices need to be paired with HV isolated gate drivers to harness the advantages such as higher switching frequency, lower conduction losses, better thermal characteristics and higher robustness at high voltages, compared to previous generation silicon-based IGBT and MOSFET power switches.
The GD316x family of advanced, functionally safe, isolated, high voltage gate drivers incorporates a number of programmable control, diagnostic, monitoring, and protection features, enhanced to drive the latest SiC power modules for automotive traction inverter applications. Its high level of integration allows a smaller footprint and simplifies the system design.
The outstanding capabilities reduce Electromagnetic Compatibility (EMC) noise while also reducing switching energy losses for better efficiency. Fast short-circuit protection times (< 1 µsec) in combination with powerful and programmable gate drive schemes optimize the performance of the traction inverter’s SiC power modules.
“Together with ZF, we are developing next-generation power electronics for future EVs,” said Robert Li, Senior Vice President and General Manager, Electrification at NXP. “Our gate driver family implements a number of outstanding features to both protect and unleash the benefits of high-voltage SiC power switches, making them an ideal choice for ZF’s new SiC-based traction inverter solutions. This collaboration is a testament to our commitment to delivering state-of-the-art solutions that enable OEMs to achieve their EV performance and sustainability goals.”
ZF traction inverters, enabled by NXP’s GD316x product family, are already on the road.
