CGD's 650V ICeGaN Devices Improve EV Range

Why It Matters

By cutting inverter losses and enabling lighter, more compact power‑train designs, the ICeGaN can boost EV efficiency and lower vehicle cost, accelerating broader adoption of electric mobility.

Key Takeaways

• 650 V ICeGaN IC reduces inverter on‑resistance to 9 mΩ
• Parallel GaN devices operate without matching performance or extra balancing parts
• Higher‑frequency switching enables smaller, lighter inverters and longer EV range
• Integrated temperature sensing improves power‑train reliability and diagnostics

Pulse Analysis

Gallium‑nitride (GaN) technology has become a cornerstone of next‑generation electric‑vehicle powertrains, offering faster switching and lower conduction losses than traditional silicon. Yet automotive designers face hurdles when paralleling multiple GaN devices, such as the need for tightly matched characteristics and additional balancing circuitry. CGD’s 650 V ICeGaN IC tackles these obstacles with an innovative interface that equalizes device operation, allowing engineers to stack chips without extra components and streamline inverter architecture.

The new ICeGaN chip delivers a remarkably low on‑resistance of 9 mΩ, slashing conduction losses across the inverter and easing thermal management—a critical factor for high‑power EV applications. Its built‑in temperature sensor provides real‑time diagnostics, enhancing reliability and simplifying system control loops. Moreover, the IC’s ability to switch at higher frequencies enables designers to shrink passive components, resulting in lighter, more compact inverters that directly translate into additional vehicle range and lower packaging costs.

From a market perspective, CGD’s partnership with GlobalFoundries expands the supply chain for high‑voltage GaN devices, positioning the company to meet growing demand from OEMs and Tier‑One suppliers. Early sampling with several automotive partners suggests rapid adoption, potentially setting a new efficiency benchmark for EV power‑trains. As automakers chase longer range and lower cost, technologies like ICeGaN that combine performance, integration, and manufacturability are poised to become integral to the next wave of electric mobility.
