PT2502 Overview
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...
