EPC has released four monolithic 100 V GaN power-stage ICs priced from $2.47 each in 3,000-unit volumes. The parts target multi-axis motor drives in humanoid robots, drones, and industrial equipment.

The new ePower Stage family — EPC23108, EPC23109, EPC23110, and EPC23111 — pulls a half-bridge together with its drivers and level shifters. Each device carries high-side and low-side GaN FETs, gate drivers, and level-shifting circuitry inside one thermally enhanced QFN package. Two parts in the family handle 35 A while the other two support 20 A, all rated for 100 V operation.

What does the integration actually buy a designer?

Putting a half-bridge, its drivers, and level shifters on a single die removes the timing-matching problems that arise when designers pair discrete GaN FETs with external drivers. That pairing is a recurring pain point whenever designers push switching frequencies high enough to shrink magnetic components. The same monolithic block also adds fast fault shutdown, safe gate control during power loss, and continuous 100% duty-cycle operation. A single-input PWM option sits on top for the simpler multi-axis motor-control layouts that robotics and drone platforms tend to use.

The takeaway: a single-die half-bridge cuts board complexity and lets designers raise switching frequency without separate-driver timing work.

What evaluation hardware accompanies the release?

EPC has also rolled out four three-phase brushless DC (BLDC) motor-drive boards: the EPC91128, EPC91129, EPC91130, and EPC91131. Each compact GaN-based inverter platform carries integrated gate drivers, current and voltage sensing, housekeeping power supplies, temperature monitoring, and protection features. Engineers can drop a complete three-phase GaN inverter into a prototype motion-control system without first building the support circuitry themselves.

The takeaway: the four boards let designers benchmark the ICs in real multi-axis motor loops without designing the inverter around them.

How is the family priced?

EPC lists the EPC23108 and EPC23109 at $3.70 each, and the EPC23110 and EPC23111 at $2.47 each, both at 3,000-unit order quantities. The price step reflects the lower current ratings of the latter pair rather than any functional cut. All four devices share the same 100 V rating and the same monolithic half-bridge architecture.

The takeaway: the price ladder tracks current rating, not feature set, so motor designers can match cost to load.

Where does the line fit in the wider market?

The release targets three adjacent use cases: high-performance motion control, synchronous rectification, and high-density DC-DC conversion. Robotics and small drones are the most visible end markets, where weight, power density, and thermal headroom all sit under tight budgets at once. GaN's switching-speed edge over silicon MOSFETs lets motor drives run at higher frequencies, which trims passive-component size and improves power density. EPC has paired the launch with a technical brief titled "From Device to Platform: EPC23108/109/110/11 100 V Integrated GaN Power Stages Simplify Multi-Axis Motor Drive Design," aimed at engineers choosing the right part for a multi-axis design.

The takeaway: the family targets compact multi-axis systems where GaN density savings translate directly into motor count or battery runtime.

What happens next?

The release adds another entry to the 100 V integrated GaN half-bridge segment, and EPC has staked its claim on monolithic packaging plus on-chip protection at sub-$4 price points. Adoption will hinge on how the EPC23108–EPC23111 parts perform in real multi-axis motor prototypes, paired with the EPC91128–EPC91131 evaluation boards during the next design cycle.
