Kyoto, Japan, July 8, 2024 – Nuvoton Technology Corporation Japan (NTCJ) has announced the launch of its groundbreaking 48V direct drive motor driver IC, designed to enhance efficiency and airflow in high-speed fan motors used in servers and industrial equipment. This innovative product addresses the rising demand for efficient cooling solutions in data centres and other high-performance environments.

Key Achievements and Features:

The new motor driver IC, KA44370A, is engineered to support 48V direct drive with a 100V-rated high-speed, high-output circuit on a compact chip. Housed in a 4mm x 4mm QFN package, it is ideal for 1U fan motors (40mm x 40mm), which are essential for modern high-density server racks. This advancement contributes significantly to reducing power consumption in 1U servers and increasing rack density.

NTCJ’s unique current feedback control technology enables low power consumption and minimal vibration, even at high speeds, expanding the airflow range of single-phase fan motors. This technology ensures stable and reliable motor start-up, even in challenging conditions such as mutual interference between multiple fan motors or reverse rotation caused by unexpected external airflow.

Why This Matters:

With the evolution of AI and the exponential increase in data processing, the number of data centers and servers is projected to rise dramatically, potentially increasing power consumption tenfold in the next decade. To mitigate this, server power supply systems are transitioning from 12V to 48V. This shift, combined with the need for compact and efficient cooling solutions, underscores the importance of NTCJ’s new motor driver IC.

The KA44370A motor driver IC integrates a 100V-rated voltage control circuit into its small package, significantly reducing the need for external components like step-down regulators by 53% compared to conventional 24V products. This reduction in power loss facilitates the integration of the driver IC into 1U fan motors, supporting high-density data processing.

Technical Specifications and Benefits:

• 48V Direct Drive Compatibility: Supports server power supply systems, reducing power consumption in data centers.
• Compact QFN Package: 4mm x 4mm package size contributes to higher server rack density.
• Efficient High-Speed Cooling: Real-time feedback control technology reduces power consumption by 30% and vibration by 20 dB, even at high speeds, ensuring optimal cooling for high-performance servers.
• Reliable Start-Up: Advanced rotation control algorithm guarantees stable restart capabilities, even in adverse conditions.

Applications:

The KA44370A is suitable for a variety of applications, including servers, base stations, factory automation (FA) equipment, and other industrial machinery, making it a versatile solution for industries seeking efficient and reliable cooling systems.
