FD1157H-Smart motor driver embedded Hall sensor


FD1157H  Smart motor driver with embedded Hall sensor
General Description
Download
FD1157H is a two 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.
¨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.
