DC Brushless Motor Driver IC PT-301E PWM Speed Controller Overview The PT301E is a universal DC brushless motor driver IC. PT301E is design for varies motor applications. PT301E driver IC can use for signal coil DC and traditional double coil DC brushless motor. This driver IC accepts the hall IC input and drives the motor coil directly without any other describe transistor. Driver IC can drive the DC brushless motor to start operation at the lowest voltage of 1.5V, but this IC can operate for a wide voltage range from 2.0V up to 6.5V. PT301E driver IC can support large current up to 400mA Applications Package: SOT-28 Single coils DC brushless motor. Traditional double coil DC Brushless motor DC 1.5V~6.5V.
