Digi-Key – Sinusoidal sensorless three-phase brushless DC fan motor driver (Microchip - MTD6505)Jun 18 2012 - Semiconductors [More Semiconductors Articles]
Microchip’s MTD6505 is a 3-phase full-wave sensorless driver for brushless DC (BLDC) motors – and is now available from Mouser stock. The device features 180 degree sinusoidal drive, high torque output and silent drive. With the adaptive features, parameters and wide range of power-supplies (2V to 5.5V), the MTD6505 is intended to cover a broad range of motor characteristics, while requiring minimum external components.
Speed control can be achieved through either power supply modulation (PSM) or pulse-width modulation (PWM). The compact packaging and the minimal bill-of-materials make the MTD6505 device extremely cost efficient in fan applications, says the company.More news from Digikey
