12v supply, 3 hall sensor, three phase brushless dc motor drive reference deisgn
this design consists of a three-hole sensor three-phase brushless dc motor pre-driver and a mosfet. it is an evaluation board that can drive a brushless dc motor with a supply voltage of 12v (typ) and a motor current of 6a (max) by adding a speed control circuit using a microcontroller to the 3 hall sensor 3-phase brushless dc motor drive circuit. it requires only one external power supply. when a hall ic is used, the logic ic can detect the direction of rotation and output a triple multiplier fg.
- 3 hole sensor three phase brushless dc motor pre-driver and output mos p n configuration
- supply voltage 12v(typ)
- output current 6a(max)
- pwm drive with 120 degree commutation.
- rotation direction switching, short braking function
- rotation direction detection output, triple fg output possible (when hall ic is used)
- speed control by mcu is possible.
