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
