PROLIFIC PT301EA
PT301EA, PT301ED DC Brushless Motor Driver IC
Rotation Frequency
The PT301Ex driver IC generates a FG signal for frequency calculation. In
general application, the Fan IC will generate a signal to indicate the rotation
frequency of different for each motor. When the motor is stopped, the FG
signal will pull high to indicate the stop of the motor was stopped.
Digital PWM Speed Control
PT301Ex applies the Pulse Width Modulation (PWM) to control motor speed.
PT301Ex can use the PWM input pin to control the motor speed. When the
PWM is high, the driver IC will drive the motor coil. On the other hand, when
the PWM is low, the driver IC will stop driving the motor coil.

Lock Protection
In order to protect the motor and reduce the powesirpdaitsion. When the
motor contacts the outside force, the Fan IC when sitvoipngdrthe coil after
the motor is lock over 0.25 seconds and retssttahre motor after stop the
motor 1.75 secnods. Figure-2 shows the timing diagram beetewn the hall
input signal and driver state. Whenever the motor stoeprs0o.2v5 second by
outside force, the Fan IC will shutdnotwo stop the driving output, and after
1.75 seconds, the Fan IC will turn onaiang.
