A4960 Description
The A4960 is a three-phase, sensorless, brushless DC (BLDC) motor controller for use with external N-channel power MOSFETs. The motor is driven using block mutation (trapezoidal drive) where phase mutation is determined, without the need for independent position sensors, by monitoring the motor back-EMF. A programmable motor start-up scheme allows the A4960 to be adjusted for a wide range of motor and load binations.
