PT2501 - 3-Phase Sinusoidal BLDC Motor Controller
The PT2501 is a three-phase, hall sensor sinusoidal brushless DC motor control chip.
The three-phase control is based on sine wave driving scheme and it is designed to reduce electrical audible noise in motor phase commutation.
On-chip +5V LDO provide voltage for logic and analog circuits operation.
PT2501 Features
* Hall sensor sinusoidal control for 3-phase BLDC
* Current limit function
* Over temperature protection from external NTC
* Motor lock protection
* Reverse function.
* PWM or DC input for speed control
* FG output for rotation speed
