Corporation (TOKYO:6502) has launched the industry's first1
digital- control-type sine-wave driver ICs for single axial fan motors,
which are used in products like refrigerators and PCs.

Single axial fans are often used in eco-efficient home appliances
requiring low noise and low energy consumption and for cooling PC
servers. With recent increases in the capacities of PC servers, as many
as 6 to 8 cooling fans are sometimes required in a single unit. In these
applications, the motors must offer low power consumption and low-noise
operation and be small.
Toshiba's new "TC78B002FTG" controls the current of the motor with a
sine wave, using a newly designed digital control circuit to do so. This
ensures that the motor rotates more smoothly than a conventional motor
with a square-wave drive, resulting in a 30% increase2 in
motor efficiency and a noise reduction of about 2dB to 3dB2,
compared to conventional products. In addition, as it is possible to
control the amplitude, the phase and the modulation of the output
wave-form externally, the motor can be configured to be compatible with
While using CMOS for the control circuit of the IC and DMOS for the
power output circuit, Toshiba has still housed the circuits in a single
package by applying the latest mixed process technology. By using a
16-pin leadless QFN type package, the mounting area is reduced by 70%
compared to existing Toshiba products3.
