PT2522 Datasheet (PTC) - Sensor-less BLDC Controller

PT2522, Sensor-less BLDC Controller

The PT2522 is a three-phase, sensor-less brushless DC motor control driver chip.

The three-phase control is based on a square /trapezoidal wave control method that detects the zero-crossing of the motor back electromotive force (BEMF).

It has a stable control and is not be affected by motor easily d
