Toshiba America Electronic Components (TAEC), a committed leader that collaborates with technology companies to create breakthrough designs, today launches a highly integrated, sine-wave driver IC (Part Number TB6585AFTG) for implementation in three-phase DC brushless motors used in fan motors of home appliances. The device enables quiet operation, low vibration, and low-power consumption for ventilation and electric fans typically used in range hoods, microwave ovens, refrigerators, dishwashers, and more.
The integrated Pulse Width Modulation1 (PWM) controller circuit of the TB6585AFTG driver IC generates a sine wave, to achieve a quiet, smooth, and very efficient motor drive for brushless motor applications of up to 45V/1.8A requirements. It is a highly integrated motor control IC with motor control logic, MOSFET predrivers, and six high-performance MOSFETs. The TB6585AFTG employs a compact, leadless, thermally efficient QFN48 7mm x 7mm package with an assembly bonding technique that improves the current handling capability by 45 percent over the previous version of the device. The product is also offered in a larger HSOP36 package—Part Number TB6585FG.
