FD036UT
Sensorless 3-phase brushless DC Motor driver
Features
PWM (pulse width modulation) speed control
Built-in FG(frequency generation) for rotation speed calculation, or RD(rotation detection) signal output for
rotation status monitoringSoft-switching technique to reduce vibration and acoustic noise
Thermal shutdown protection
Lock protection and auto-restart function
Selectable direction of rotation(FD036UT)
Low stand-by current in Disable mode(FD036UT)
General Description
FD036 is a sensorless 3-phase brushless DC motor driver. It senses the BEMF(Back-ElectroMotive Force) of the
motor in rotation and provides corresponding commutation current to the motor. The use of sensorless technology
means no Hall sensors are needed. The absence of the Hall-sensor makes the fabrication of the motor easier and is
especially suitable for ultra-small motors since the motor driver IC is placed outside the motor assembly.
