PT2502 3-Phase Sensor-less BLDC Motor Controller DESCRIPTION PT2502 is an integrated 12V 3-phase sensor-less (no Hall sensor required) BLDC motor controller. Threephase motor control with square/trapezoidal wave is based on detecting a zero-crossing signal generated from the motor back-EMF (BEMF) and provides robust control stability that is not easily affected by different motors. Soft-switching control technology outputs trapezoidal/quasi-sinusoidal-wave current and further reduces audible electro-current noise. PT2502 provides an internal +5V voltage regulator to supply power to the analog and digital blocks. For 400V high-voltage motor control applications, an external high voltage gate driver and six N-channel MOSFETs are required.
