Efficient Power Conversion (EPC) has commenced mass production of its 100 V integrated gallium nitride (GaN) power-stage IC family, which includes the EPC23108, EPC23109, EPC23110, and EPC23111 models. These ePower™ Stage ICs are engineered for high-performance motion-control applications and integrate high-side and low-side eGaN® FETs, gate drivers, and level-shifting circuitry into compact, thermally-enhanced QFN packages. Designed for optimal power density and efficiency, these devices aim to simplify system design while offering current ratings of 35 A and 20 A, depending on the model.
The new power-stage IC family features rapid fault shutdown, safe gate control during power-loss scenarios, and continuous 100% duty-cycle operation, making them suitable for various applications. For multi-axis motor-control applications, single-input PWM options are available. Additionally, EPC offers the EPC91128, EPC91129, EPC91130, and EPC91131 three-phase BLDC motor-drive evaluation boards, which are designed around these new power-stage ICs. These platforms come equipped with gate drivers, current and voltage sensing, housekeeping power supplies, temperature monitoring, and protection functions.
Available through EPC’s global distribution network, including partners like Digi-Key and Mouser, these devices are poised to serve a range of applications. These include humanoid robots, drones, industrial motor drives, medical equipment, synchronous rectification, and high-density DC-DC converters. Pricing for the EPC23108 and EPC23109 is set at $3.70 each, while the EPC23110 and EPC23111 cost $2.47 each, based on orders of 3,000 units. The evaluation boards, EPC91128 and EPC91129, are priced at $640 each, with the EPC91130 and EPC91131 coming in at $630 each.
EPC is also releasing a technical white paper available in both English and Chinese. This document will cover the architecture, design considerations, and evaluation platforms for these new integrated GaN power-stage ICs, providing detailed insights into their capabilities and applications.
