Feeling Technology FD0255b

the FD0255b will generate PWM pulses internally with the “ON” duty cycle ratio according to the diagram below(Figure.3), which can be utilized by the user to control the speed of the motor. The rotation speed will be higher if the voltage applied to the PWM pin is higher. The FD0255b will pass this pulse to the coil driver with the original duty-cycle ratio.

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 and FD0255b. “Soft-switch” phase-switching technique is used to reduce the vibration and acoustic noise.
