Overview
FEELING TECHNOLOGY Features FD0251f FD0255f Smart motor driver with embedded Hall sensor Motor driver with integrated Hall sensor Halogen Free High current driving capability Lock-shutdown protection & auto-restart function Built-in FG(frequency generation) signal outputPrecise magnetic switching thresholds “Soft-switch” phase-switching technique to reduce vibration and acoustic noise(patent pending) Thermal shutdown protection PWM speed control(only available for FD0255f) Available in both TS825(FD0251f) and TS826(FD0255f) packages General Description FD0251f/FD0255f is a single coil motor driver with embedded Hall sensor.
It integrates the motor driver with the Hall sensor, which simplifies the PCB(printed circuit board) design and make the fabrication of small-size motors possible.
Lock-shutdown and auto-restart function keeps the motor from being over-heated and restarts the motor after being locked.
“Soft-switch” phase-switching technique is used to reduce the vibration and acoustic noise.
Thermal-shutdown protection ensures the motor driver to operate under specified temperature ranges.
All the protection mechanisms mentioned above combine to provide a complete protecting scenario for the motor system, keep the motor system from possible damages and guarantee correct operations.
