- The ET1215Q is a Three-Phase Sinusoidal BLDC Motor Driver. It comes with the advanced Hall sensor design and users can choose to use 1 Hall or 3 Halls according to the actual conditions. Due to its adaptive features and wide power-supply range capabilities, it is intended to cover a wide range of motor characteristics, while requiring little 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 ET1215Q are comprehensive including lock protection and automatic recovery, under voltage, thermal shutdown, current limit and over current protections. These prevent the control circuits and the motor from being damaged, particularly under stressed applications and demanding environments.
