iT8321E: Code-Free, All-in-One BLDC Driver Enabling the Next Evolution in Computing Thermal Management — Cooling the Planet Together
Hsinchu – May, 2, 2025 – As demand continues to surge for high-performance computing applications such as image processing and deep learning, thermal management systems must evolve in parallel. The industry trend leans toward high efficiency, outstanding thermal performance, and compact form factors. The key challenge lies in enhancing cooling capabilities without increasing physical footprint. There is growing demand for cooling solutions that are not only highly reliable but also cost-effective. In addition to ongoing advancements in air-cooling efficiency and innovation in product design, materials, and mechanical structures, liquid cooling has gained momentum thanks to its superior thermal performance and silent operation. As liquid cooling technology matures and becomes more affordable, its adoption is accelerating in gaming, workstations, and high-end computing systems.
The iT8321E is a all-in-one single-phase brushless DC (BLDC) motor driver IC that supports both 5V and 12V systems with a maximum current of 2.1A. Engineered to meet the stringent thermal requirements of high-performance computing, the iT8321E provides an efficient and compact solution for small form factor liquid cooling systems. Its code-free design significantly reduces the engineering effort required for software validation, helping developers accelerate project timelines. Compared to discrete component solutions, the all-in-one architectures simplifies system design, reduces bill-of-materials (BOM) costs, and minimizes PCB footprint.
With built-in MOSFETs and Hall sensors, the iT8321E supports a variety of optimized control options. Combined with the intuitive inergy GUI, engineers can quickly fine-tune motor parameters to achieve low noise, low vibration, and high efficiency. Configurable soft start modes ensure stable and reliable motor initialization, prolonging product lifespan. The driver supports both open-loop and closed-loop speed control. The product series features robust protection mechanisms, including over-voltage, under-voltage, current limiting, over-current, over-temperature, lockout protection, and automatic recovery. These features greatly enhance application safety and reliability. inergy Technology continues to deepen our expertise in thermal management, offering dependable, long-life solutions that meet rigorous performance standards - delivering ideal cooling for high-end computing while contributing to a cooler planet through energy-efficient operation.
