General Description
FD0252f/FD0256f 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. FD0252f/FD0256f is built-in the signal output of rotation detection function, the system could detect the rotation status from this signal of motor when using FD0252f/FD0256f. “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.
