Application Specification
FT310 chip is designed for Three-Phase sensorless brushless DC motor, and is suitable for low voltage and high current application. FT310 sensorless BLDC drive IC allows the removal of rotor position sensors such as Hall Sensors, and can simplify the motor structure. This can save cost and yet improve 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. FT310 has robust starting capability. Robustness of starting is preserved whilst configuration of starting parameters is largely simplified with turning of a few external resistors. Its unique control algorithms can keep the motor in high efficiency running. The chip can stand DC6V to 28V wide input voltage, and is high temperature resistant, good ratability, low power consumption, adaptive inverse voltage detection, integration, MOSFET front drive, peripheral devices and so on. The chip can also realize soft-start, speed control, reverse, braking, locked-rotor protection, overheat protection, over current, under voltage protection, cross-protection and so on.
     Application Features
FT310 is designed according to strict industrial standards. The chip is produced by advanced DMOS processing, and can meet many industrial and commercial application needs. It is especially suited for the applications under severe environment conditions, and can also stand the power voltage range from DC6V to DC28V. Currently, FT310 is widely used in many areas with strict requirements (including the automotive, industrial, telecommunication and office equipment ), such as electric vehicles, industrial fans, electric tools, household appliances, message devices, printers and applications of various kinds of cooling fan.
