Description

The MTD6505 device is a 3-phase, full-wave sensorless driver for brushless DC (BLDC) motors. It features 180° 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 PSM or PWM.
