EPC begins mass production of 100 V integrated power stage ICs designed to simplify motor control for robotics, drones and compact battery-powered technologies
El Segundo, California, 1 September 2026 – The race to make robots, drones and other intelligent machines smaller, faster and more energy efficient is creating new demands on power electronics. Addressing this need, Efficient Power Conversion Corporation has started mass production of a new family of 100 V integrated gallium nitride power stage ICs designed for high-performance motion control.
The new products, known as EPC23108, EPC23109, EPC23110 and EPC23111, combine several important power components into a single compact package. The devices bring together high-side and low-side GaN transistors, gate drivers and level-shifting circuitry, reducing the number of separate components engineers need to work with when designing a motor control system.
In simple terms, these ICs are designed to help machines control motors more efficiently while taking up less space. This is particularly important for technologies such as humanoid robots and drones, where several motors may need to operate simultaneously inside a compact system.
GaN, short for gallium nitride, is a semiconductor material that can support fast switching and high power efficiency. These characteristics make it attractive for modern power systems where designers need to reduce energy losses and increase power density.
EPC’s new devices can operate at up to 100 V and offer current ratings of either 35 A or 20 A, depending on the model. They are housed in thermally enhanced QFN packages designed to help manage heat while keeping the overall power stage compact.
The company has also built protection features into the new family. These include fast fault shutdown and controlled gate behavior when power is lost. The devices can also operate continuously at 100 percent duty cycle, a feature that can be important in motor applications requiring full and uninterrupted power.
Another feature is the availability of single-input PWM options on selected models. PWM, or pulse width modulation, is a common method used to control the amount of power delivered to a motor. Simplifying this control connection can be useful in systems that have several motors operating across multiple axes.
The technology has clear applications in robotics. Modern robots can contain numerous motors responsible for movement in joints, arms and other mechanical systems. Reducing the size and complexity of each motor drive can help engineers manage space, heat and power more effectively.
Drones are another important application. Battery-powered aerial systems need to balance motor performance with limited battery capacity. More efficient power electronics can help designers make better use of available energy while maintaining the performance required for flight.
Beyond robotics and drones, EPC says the new power stages can be used in industrial motor drives, medical equipment, synchronous rectification and high-density DC-DC converters.
To help engineers test the technology, EPC is also offering four three-phase brushless DC motor drive evaluation boards. The EPC91128, EPC91129, EPC91130 and EPC91131 platforms incorporate functions such as current and voltage sensing, temperature monitoring, power supplies and protection. These boards give developers a practical way to evaluate the new ICs before incorporating them into their own products.
The move into mass production is significant because it takes the technology beyond the development stage and makes the devices available for broader commercial use. EPC says the products are being offered through its global distribution network, including Digi Key and Mouser.
The development also reflects a wider trend in the semiconductor industry. As robotics, automation, drones and battery-powered machines become more sophisticated, engineers are looking for power solutions that can deliver higher performance without increasing system size.
Integrated GaN power stages could help address that challenge by combining multiple functions into a single device. This can simplify circuit design, reduce component count, and potentially make it easier to build compact power systems.
For the growing robotics and advanced motion control markets, the importance of efficient power management is likely to increase. As machines become more capable, the electronics controlling their motors will need to become equally sophisticated.
EPC’s latest production launch shows how GaN technology is moving further into real-world applications. By combining high-speed switching, integrated control and protection features in a compact package, the new devices are designed to give engineers another tool for building the next generation of efficient and space-conscious machines.
