Smart motor driver with embedded Hall sensor
Motor driver with integrated Hall sensor Halogen High current driving capability Free Lock-shutdown protection & auto-restart function Built-in FG(frequency generation) signal output “Soft-switch” phase-switching technique to reduce vibration and acoustic noise Thermal shutdown protection PWM speed control(only available for FD0255b) Available in both T825(FD0251b) and T826(FD0255b) packages
GENERAL DESCRIPTION
FD0251b/FD0255b 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. FD0251b and FD0255b are built-in the signal output of rotation speed function, the system could detect the rotation speed of motor when using FD0251b...
