DATA SHEET
FT310N
Description
Sensorless BLDC Motor Controller
With N-channel MOSFETs Driver
Feature
The FT310N is a Three-Phase sensorless Brushless
DC motor controller with N-channel MOSFETs driver
that provides commutation and PWM current control.
FT310N Sensorless BLDC drive chip allows for the
removal of rotor position sensors such as Hall
Sensors, and simplification of the motor structure.
This provides for savings in cost yet improving the
reliability of the motor system. As the number of
connection between the motor and drive is reduced,
the assembling is simplified and testing of the motor
system is straightforward. Being sensorless, the
motor driver can be installed out of the motor body,
and this allows for flexibility in the design and
extension of its application.
FT310N has robust starting capability. Robustness of
starting is preserved whilst configuration of starting
parameters is largely simplified with tuning of a few
external resistors.
