10-Lead 3mm x 3mm UDFN The MTD6505 device is a 3-phase, full-wave
sensorless driver for brushless DC (BLDC) motors. It
features 180В° 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.
