DC Brushless Motor Driver IC
Frequency Output
PT-3016x
Divide 1/1.5/2
Overview
The PT3016x is a universal DC brushless motor driver IC. PT3016x is design for varies motor
applications. PT3016x 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. PT3016x driver IC can
support large current up to 400mA
Applications
Single coils DC brushless motor.
Traditional double coil DC Brushless motor
DC 1.5V~6.5V.
