San Jose, Calif. − Toshiba America Electronic Components, Inc. (TAEC) has introduced an integrated, sine-wave motor driver IC for three-phase DC brushless motors, which are used in fan motors for home appliances. Touting energy savings for home appliances, the TB6585AFTG device is said to enable quiet operation, low vibration, and low-power consumption for ventilation and electric fans typically used in range hoods, microwave ovens, refrigerators, and dishwashers.
The device's integrated pulse width modulation (PWM) controller circuit 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, said TAEC. Other features include motor control logic, MOSFET predrivers, and six high-performance MOSFETs.
The TB6585AFTG motor driver IC is housed in a leadless, thermally efficient QFN48 7- x 7-mm package with an assembly bonding technique that improves the current handling capability by 45 percent over the previous version of the device, according to TAEC. The product is also offered in a larger HSOP36 package (Part Number TB6585FG).

Availability: Mass production is scheduled to start in July 2013.
Pricing: One piece sample pricing for the TB6585AFTG is $3.00.
