• 100 V rating supports up to 35 A current for demanding loads
• Single‑pin PWM options reduce wiring complexity in multi‑axis robots
• Built‑in safety features ensure deterministic shutdown and fault tolerance
• Available through DigiKey and Mouser for rapid prototyping

Pulse Analysis

Gallium‑nitride (GaN) technology has become the cornerstone of high‑efficiency power conversion, offering superior switching speeds and power density compared with traditional silicon. As robotics, unmanned aerial vehicles and compact DC‑DC converters demand ever‑higher performance in smaller footprints, designers are turning to monolithic solutions that integrate power devices, drivers and protection circuitry. EPC’s new 100 V GaN power‑stage family arrives at a time when the market seeks to eliminate bulky gate‑driver boards and reduce parasitic losses, enabling tighter thermal budgets and longer battery life for battery‑powered platforms.

The EPC23108‑23111 series consolidates high‑side and low‑side eGaN FETs, gate drivers, level shifters and safety logic into a single QFN package. By offering up to 35 A continuous current and 100 % duty‑cycle capability, the devices support full‑torque motor operation without complex dead‑time modulation. Features such as an active‑low fast‑shutdown, built‑in pull‑up resistor and deterministic gate pull‑down protect against fault conditions, while single‑pin PWM inputs streamline multi‑axis motor‑control boards. This integration reduces bill‑of‑materials, shortens PCB routing and simplifies firmware, delivering measurable cost and time‑to‑market advantages for OEMs developing humanoid arms, multi‑rotor drones and Class‑D audio amplifiers.

From a market perspective, EPC’s expanded portfolio positions the company alongside rivals like Texas Instruments and Infineon in the fast‑growing GaN power‑stage segment. The availability through major distributors accelerates prototype cycles, encouraging early adoption in niche applications that demand reliability and compactness. As supply chains stabilize and GaN wafer costs decline, the broader industry can expect a shift toward fully integrated GaN modules, driving higher efficiency standards across automotive, industrial and consumer sectors. EPC’s focus on customer‑driven features—such as single‑pin PWM and deterministic shutdown—demonstrates a trend toward application‑specific GaN solutions that directly address the challenges of high‑performance motion control.
