Realizing Quiet Drive and Low Energy Consumption for Home Appliances
TOKYO — (BUSINESS WIRE) — July 30, 2013 —
Corporation (TOKYO: 6502) today announced that it has launched a
sine-wave driver IC, TB6585AFTG, for the three-phase DC brushless
motors used in the fan motors of home appliances that require quiet
operation and low energy consumption, such as ventilation fans and
electric fans. Mass production shipment starts today.
The integrated PWM1 controller circuit of driver IC generates a sine wave, realizing a quiet, high efficiency motor drive.
The TB6585AFTG adopts a small, leadless, heat-dissipating QFN48 package that realizes the same absolute maximum ratings for voltage and current as existing products2. The driver IC contributes to equipment downsizing and lower PCB costs by reducing the required mounting area by approximately 75%.
