Features

and wide power-supply range capabilities, it is intended to cover a wide range of motor characteristics, while requiring minimal tuning from the user. Speed adjustment can be achieved through either direct-PWM or analog voltage control. Speed indicator is provided through a Frequency Generator output, generating digital pulse with its frequency proportional to the speed of the motor. Protection functions of FT3216 are comprehensive including lock protection and automatic recovery, under voltage, thermal shutdown, current limit and over current protections. These prevent the control circuits a.
