| DC Brushless Motor Driver IC PT-30DFX Single- Phase Full-Wave Linear Drive The PT30DFx is single-phase full-wave driver IC. This driver IC can be used for single coil DC brushless motor. This driver IC accepts the hall IC's output signal and drives the motor coil directly without any other extra transistors. This IC can be operated from 2V to 18V supply voltage and driving current can be up to 400mA. APPLICATIONS Single coils DC brushless motor. DC 2.0V~18V.
