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.
