FT310S

DATA SHEET FT310S Sensorless BLDC motor controller With power MOSFETs driver Description Feature The FT310S is a Three-Phase sensorless Brushless DC motor controller with direct external MOS driver that provides commutation and PWM current control. FT310S 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. FT310S 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)  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 Output current Logic input pin withstand voltage RD/FG output pin withstand voltage RD/FG o...
