Overview
FEELING TECHNOLOGY FEATURES Motor driver with integrated Hall sensor High current driving capability Lock-shutdown protection & auto-restart function Built-in RD(rotation detection) signal output “Soft-switch” phase-switching technique to reduce vibration and acoustic noise Thermal shutdown protection PWM speed control(only available for FD0256b) Available in both T825(FD0252b) and T826(FD0256b) packages FD0252b FD0256b Smart motor driver with embedded Hall sensor Halogen Free GENERAL DESCRIPTION FD0252b/FD0256b 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.
FD0252b/FD0256b is built-in the signal output of rotation detection function, the system could detect the rotation status from this signal of motor when using FD0252b/FD0256b.
“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.
