KYOTO,
Japan, July 22, 2024 /PRNewswire/ -- Nuvoton
Technology Corporation Japan (NTCJ) announced on July 8 the launch of a new 48V direct drive motor
driver IC that enables high efficiency and high airflow with high
speed rotation in fan motors.

- The newly developed motor driver IC incorporates a 100V-rated
voltage control circuit, based on the high-voltage control circuit
technology that NTCJ has cultivated over the years, into a small
4mm x 4mm QFN package, while significantly reducing external
components such as step-down regulators (53% reduction from the
conventional 24V product). This reduces power loss and enables
installation onto 1U-size (40mm x 40mm) fans, contributing to
high-density data processing.
- The high-speed data processing of the AI server requires the
fan motor to rotate at a higher speed in order to cool down the
increasing heat generation. Simultaneously, it is necessary to
suppress the rising trend of power consumption in fan motors, and
its vibrations that adversely affect the HDD error rate. NTCJ's
proprietary technology for real-time feedback control of motor
drive current value and phase with high resolution makes it
possible to reduce the power consumption of single-phase fan motors
by 30% and vibration by 20 dB compared to conventional motors, even
at high speeds when higher airflow can be output. This contributes
to high-speed, large-capacity data processing that requires high
cooling capabilities.
- In general, it is difficult to detect reverse rotation in a
single-phase fan motor. So, when the fan motor stops and there is
interference in between multiple fans, or when the fan motor
rotates in reverse due to disturbances such as the inflow of
external air, it is difficult to restart the fan motor in
conventional products. However, NTCJ's proprietary rotation control
algorithm can achieve reliable and stable restart even from reverse
rotation speed that is twice as high as the conventional
products.
