FT320

FT320 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) output  Over current protection  Built-in lock protection and automatic recovery circuit (External capacitor not necessary)  Built-in thermal shutdown protection(TSD)  Built-in under voltage lock out (UVLO) Specifications Absolute Maximum Ratings (@Ta=25℃) Parameter Power supply voltage Symbol VCC max VM max Output current IOUT max Logic input pin withstan...
