FT320
Three phase sensorless BLDC driver
For low noise and low power motor
Description
Feature
The FT320 is a Three-Phase sensorless Brushless
DC motor driver for low noise and low power motor.
FT320 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.
FT320 has robust starting capability. Robustness of
starting is preserved whilst configuration of starting
parameters is largely simplified with tuning of a few
external resistors.
Position sensorless BLDC controller (No hall
sensor required)
Two speed control can be selected( direct-PWM
and analog control)
Low power standby mode
FG (Frequency detection) and RD (Lock detection)
