PT2505 Overview
The PT2505 is a three-phase, hall sensor sinusoidal brushless DC motor control chip with different protection mechanism. The three-phase control is based on sine wave driving scheme and it is designed to reduce electrical audible noise in motor phase mutation. On-chip +5V LDO provide voltage for logic and analog circuits operation.
