EPC Mass Production Update Adds 100 V GaN Options for BLDC Drives

Industry Update

Efficient Power Conversion said on August 26, 2026 that its 100 V integrated GaN power-stage IC family has moved into mass production. The family includes EPC23108, EPC23109, EPC23110, and EPC23111 devices for high-performance motion-control and compact power-conversion designs.

According to EPC, the monolithic ePower Stage ICs combine high-side and low-side eGaN FETs, gate drivers, and level-shifting circuitry in a thermally enhanced QFN package. The devices support operation up to 100 V, with current ratings listed at 35 A and 20 A across the family.

The company also points to fast fault shutdown, gate control under power-loss conditions, 100% duty-cycle operation, and single-input PWM options for multi-axis motor-control designs. EPC says the devices are available through its global distribution network with Digi-Key and Mouser as production ramps up.

For engineering teams evaluating BLDC motor-drive layouts, EPC also offers EPC91128, EPC91129, EPC91130, and EPC91131 three-phase BLDC motor-drive evaluation boards. These compact inverter platforms are built around the same IC family and include gate drivers, current and voltage sensing, housekeeping power supplies, temperature monitoring, and protection features.

Buyer Considerations

For motor buyers and equipment builders, the practical point is not simply the use of GaN. It is whether a compact inverter power stage can meet the voltage, current, heat, protection, and controller-interface requirements of a specific BLDC motor or motion axis.

Robotics, drone, medical-device, and compact automation projects often place tight limits on inverter size and cooling. Buyers comparing drive architectures should confirm the continuous and peak current needs of the motor, the expected ambient temperature, available airflow or heat sinking, and the required fault-response behavior before selecting a power stage or evaluation platform.

The update may also help sourcing teams separate design-sample availability from production availability. A component family moving into mass production can be relevant when OEMs need repeatable supply, distributor access, and a clearer path from prototype inverter boards to production motor-drive assemblies.

Engineering teams should still validate switching frequency, electromagnetic compatibility, current sensing, thermal margin, firmware behavior, connector strategy, and motor protection with their own load profile. Evaluation boards can shorten early testing, but they do not replace application-level qualification.

Frequently Asked Questions

What changed in EPC's latest announcement?

EPC said its EPC23108, EPC23109, EPC23110, and EPC23111 100 V integrated GaN power-stage IC family is now in mass production, with related BLDC motor-drive evaluation boards available for development work.

Does this affect complete motor selection?

It can affect the drive electronics side of a BLDC motor system. Buyers still need to match the motor, gearbox, encoder, controller, thermal design, load cycle, and protection requirements as one system.

Which applications could be most relevant?

EPC lists humanoid robots, drones, industrial motor drives, medical equipment, synchronous rectification, and high-density DC-DC converters. For motor buyers, the strongest fit is likely compact BLDC motion systems where inverter size, response, and thermal margin matter.

What should engineers verify before using these devices?

Engineers should verify bus voltage, continuous and peak phase current, cooling conditions, PWM interface, shutdown behavior, sensing accuracy, electromagnetic compatibility, and distributor availability for the intended production schedule.
