Toshiba Electronics Europe has launched a compact and efficient sine wave driver IC for control of three-phase DC brushless motors in electric fan applications. The TB6585AFTG will suit ventilation fans and fans in home appliances that require quiet operation and low energy consumption. Mass production of the new IC started last month.
The integrated PWM controller circuit of the driver IC generates a sine wave, realising 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 products in larger packages. By reducing the required mounting area by approximately 75%, the driver IC contributes to equipment downsizing and lower PCB costs.
