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.
