Product Overview
The FT1128 is a Three Phase sinusoidal Brushless DC (BLDC) Motor controller with a built-in driver. It comes with Hall insensitive sensor design providing both SVPWM and BLDC drive with constant/variable lead angle. Open/Closed loop speed adjustment can be achieved through either direct-PWM or analog voltage, initiated by soft-start. Speed indicator is provided through a Frequency Generator output, generating digital pulse with a configurable frequency proportional to the speed of the motor. Protection functions of FT1128 are comprehensive including lock protection and automatic recovery, under voltage, thermal shutdown and current limit protections. These prevent the control circuits and the motor from being damaged, particularly under stressed applications and demanding environments.
